Well, I answered your question.   I made a living analyzing automotive materials. When someone asks a question I give an answer based on lab work, engine test cells data, teardown of those t

Since Dizzy uses so much oil a 3K mineral oil cleaning was still beyond her ability so I broke it into two 1,500-mile segments. Yea, cost twice as much. I'm good with that.    At the end of

Guess I'm the ant at the picnic. :) Let me say this up front. Good points all.

 

Now, having said that, let me toss this out there. SYNERGY

 

It isn't this or that. It's this and that and that and that. There is no perfect base. There are some darn good blends. There are some that are basic. Some worse. A few much worse. 

 

There is no perfect add pack. There are add packs that work well with specific blends of bases. 

 

There isn't a Nirvana. There is best KNOW current compromise. 

 

What works against this is PROFIT MARGINS. Greed is obscuring the truth. 

 

Mobil tossing POE under the bus was not a performance move. It was a profit move. They have been in and out of the Tri-synthetic market (PAO/POE/AN) more often than Uncle Vinny in a $20 hooker.

 

Dad and Uncle pushed Fords past 750 K and to a MILLON on straight cut dinosaur oils on REALY SHORT OCI's.

 

Matching a chemistry to an OCI is key.  The fight is over OXIDATION (OCI) not wear. 90% of the public doesn't even care about wear rates. They trade to often and don't give a rat's back side about the next guy. Puppy Pee with get you to 60K.

You had mentioned in response to my longevity question about changing the engine once it failed. You’re answer was the body is giving up do to the winter in your area. It sounds like a daily driver in your neck of the woods is good for 8-10 years max. Probably 200K miles for most people. 5K oil changes with most any synthetic will do the job. For most vehicles. The general feeling across the board is most vehicles will reach 200K miles sold today. Even after all your efforts it seemed you had an oil burner after 100K miles. I wonder if it would have made 200K if you did nothing but added oil.

I'd like to see this granular of a discussion about gasolines and diesel fuels. Then look at what they do to our engines that our oils can't correct for.    Grandaddys fuels and their post combustion products were not recirculated into his engines, they went out the draft tube. Remember the dark part of the blacktop and concrete that was in the middle of the lane???? That's were all that crap went we now re-ingest.

My last collector vehicle was a 64 elcamino. It had the canister oil filter and that tube. You could smell the blow by. We still have a 2000 Ford 7.3 and a 98 Ram with the Cummins. My mother just passed 240K miles with it. They both have been bulletproof. All free of the latest emissions. Both get better fuel mileage than the current models. My brother has about 6 newer Ford and GM diesel for backup for his ROW crews. He used to keep two around. Non are as reliable with the latest emissions. There’re different animals after being deleted.

I agree Grumpy synergy is key.  There is no chemical panacea.  

 

Mobil 1 has excellent oxidation resistance.

I wonder if it would have made 200K if you did nothing but added oil. 

 

If you recall a UOA at 80K showed the motor was 'eating" itself. Iron. Aluminum. Stuck rings. Simply adding oil would not have freed them and the destruction would be complete and in shorter order than long. Lack of ring seal drastically shortens oil life and my response to that was a drastically shorter OCI. Again, based on UOAs at the time. Viscosity break was horrible. So, if I had stayed on 5K OCI's and simply added, this motor would have mechanically failed well before 150K. A lesson learned in my teens (first few cars). 

 

Pepper is now 9 years old and as solid as she was the day I bought her, 180K pretty soon. Very different life in the exact same environment. Daisy is 16 years old and will pass for new even in the nooks and crannies. Last thee Hondas went 18 to 20 years before the body died. All in daily service. 

 

We've been looking at a replacement for Dizzy and it has been heartbreaking. I am rapidly coming to the conclusion that I can do the repairs required and be half as deep in cost and get twice the vehicle as a result. Including the body work.

Fuels would be a really interesting topic to dive deeper into IF we had the choices we have in motor oils. And I guess to a certain extent we do. We just have less information to work with. I have one Flex Fuel capable vehicle and I use E85 in it. The remaining ones I use Top Tier and occasional PEA or Propylated, Aminated systems cleaners. Techron, Red Line S1, AMSOIL P.I., GUMOUT Regane. 

 

Sidebar. As a motor ages and ring seal fades and inlet guides weep oil ingress to the power cylinder increases the octane requirement. Not due to carbon build and compression pressure increase, although that can be a player, but because oil mixed with fuel KILLS octane rating. 😉  ECU KR response can only take out so much timing.

I’m probably happily stuck with my avalanche for life. I keep looking, that never stops. If I find a nicer one for a reasonable price I’d buy it. Same with the other two. I can’t believe how well my wife’s car has aged. I’m in good climate so that’s not a factor. I’m good with hanging on to them now.

There is no oxidation issue in current spark engines. There is less oxidation issues in compression engines. 
 

Nitration yes. There are no good anti noxidant additives but the oil and chemistry industry want you the consumer with a bit of knowledge about oil analysis to believe anti oxidants which are cheap really matter. Food for thought. More marketing crap.

Once again Grumpy you are posting info on BURNING METHANE via spark engines.  Not applicable necessarily to our engines using gasoline or gasoiline ethanol mixes. 

 

When I worked for WOO sprint car race series as the oil analysis rep and we burned methanol in our 410 engines before switching to ethanol we had a separate set of issues. 

 

You can't just go to interwebs and pull spurious unrelated tech data to prove your point which is based on lack of R&D level knowledge. 

 

Gosh I sound smart again, the meds are working....better living through chemistry MOFO's! Story of my life. 

 

Learn for yourselves kids.  Take an oil analysis from any cheapass source you can find that can keep their FTIR tuned accurately. ( check out RUSH truck centers for a cheap source but make sure the techs and mechs haven't kicked it or blown cigarette smoke into their little box size analyzer before they run your sample)   Sample your engine oil brand clean and run against a used sample looking at NITRATION vs OXIDATION  tell me which one shows movement purely via starting value vs ending on used.   Thats not an accurate reading via science interpretation but one that will convince.  

 

Nitration ambient clean will NOT carry over to a fired engine oil .  So consider starting nitration 0 on clean oil via FTIR, Near IR, or Raman.

 

Oxidation ambient is a measure of clean oil construct but the used value won't rise much more than 5 abs units because oxidation is low in modern engines first and secondly oxidation phase inhibiters are so cheap and effective they will neutralize any harmful oxidation until the oil is overused OR there is a serious fuel or mechanical issue.

19 F-150 3.5EB, 14.4k HPL No VII Euro 5w30

 

14k miles on HPL No VII Euro 5w30.  My question is, if the virgin oxidation value starts at 23 for this oil, but is now 48, is that a problem or sign of oxidation?  I have noticed that Amsoil's virgin oxidation number doesn't change much from virgin to new.

The HPL is cleaning the heck outta that EB carbon maker. It’s real oxidation and the HPL is measuring a SAE 40 because of it. 
Detectable soot = cleaning going on and or your tune efficiency not  optimum. I’d change out the oil filter and top up. Change plugs , air filter, and ask HPL to do a GC for fuel’s dilution. No way this is an accurate fuel’s dilution. 
Thanks for sharing.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      By Chuck FB · Posted

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.
