  1. 277,000 Mile Service 445,788 km 10/23/2025 1,000 OCI nominal 8 ounces of makeup oil (no oil in the breather this go) 5 Quarts Mobil 1 Euro FS 5W40, 1 FRAM CH9018 filter
  2. Another Wear Study There is little difference in wear absolute between 170/180 F and 212 F. There is zero difference in heat up times between the two thermostats to 170/180 F. Colder thermostats do not significantly increase wear. They do lower oil oxidation rates. What is the viscosity of an SAE 0W20 at 40 C/104F? And an SAE 5W40? Contemplate the difference in wear between that caused by running at 100F vs the few centistokes difference in viscosity at 212 F or a single centipoise at 150 F (ring area) and tell me with a straight face running a 5W40 increases bore or bearing wear based on it's viscosity. Corrosive wear at 60 F isn't a function of viscosity. https://rotella.shell.com/en_us/info-hub/4-ways-engine-wear-tear-occurs.html
  3. Mine has used a bit a year since new. Now 191,300 miles. Never see a leak. It isn't much and if it is leaking I'll not find it at this rate of loss. Holds a standard pressure test with ease. I'm not randomly swapping parts to chase it. I read from a supplier of silicon radiator hoses that all hoses are 'permeable'. Silicon more so than factory but all are permeable.
  4. $3.09 most stations today. Up 37 cents, 13.6% from the short lows. Lows went up and highs came down.
  5. Some stations are inching off their lows. $2.72 A few never did drop a single cent. $3.39 Pretty wide spread locally.
  6. If a person judges a powertrain as good if it is still moving then Dizzy at 300K then one would say whatever I've done was a success and no need to do better. But the truth is this motor is junk and has been junk since before 100K if success is judged by oil consumption and usable power and 'trust' $$$$ spent keeping it no better than 'functional'. Both ways are but 10% to 30% of an OTR's MINIMUM expected life span. Making it sound as if they are the same is dishonest. Arguments otherwise are not arguments of the physical facts but rather arguments of personal viewpoints and limits of personally acceptable standards. There isn't a method I know of that will allow comparing the two. If I require flawless paint that means nothing is set on the car period. If you are good with using your hood as a workbench then we can't argue one method is better than the other. And yet, we are both happy with the result. Pepper is now 2.4X further down the road than Dizzy's failure point. Failure being the milage she started to use an unacceptable amount of oil. I've spent nothing on Pepper in non-routine motor maintenance. I've spent thousands on Dizzy. I'd drive Pepper to wherever the mood strikes me and Dizzy to under a 50 miles one way. But hey, that's my standard.
  7. I'm considering block heater. Not practical in the pickup as it has a minimum low temperature where it will even turn on without coding the EUC but the Mitsubishi has a place cast into the block for one. We have what we 'know'. What were are accustom to. That is if we drive a certain way and sample we get used to seeing a certain pattern of wear. We relate that to being "normal' and it is for that set of conditions. But how low can it go with attention to the broader view of operations? This tiny motor, big boost thing going on is hammering the "LOAD" part of the equation. In those papers I gave numbers for there is a graph that shows that there is considerable wear difference between low load down the road BMEP and WOT or sustained 4K operations under same, as in towing. There is absolutely a trade made between wear and thermal efficiency and the consumer is not winning that trade.
  8. Beat a new Drum I rarely start Pepper for a drive under 100 miles. Rarely, not never... Why? How much time and how many threads I've I spent talking about the reduction of wear? Yea...a lot. News flash. Those discussions fall into the 25% of the engines total wear you have the most control over. After it's heated up. 75% of engine wear happens between ambient, cold start, and 160 F+. Not just water temperature but bulk oil temperature as well. Oil takes a much longer time to bring to fully warmed up than does the water. SAE Tech Paper 2006-01-3413 (One of the GM studies) SAE Tech Paper #600190 Standard Oil wear during cold start Ring/bore life is the limiting factor in overall engine life, not bearing life. Ring and bore life hinge on the oil, oil condition and in its operating environment, the number of miles PER COLD START, and load. Yes there are more factors but these are the heavy hitters. OTR engines get a cold start or two a day and then are run for 400-600 miles. Soccer mom's van almost never attains 160 F oil temperature between starts. One goes a million miles the other ??????? Go figure
  9. I honestly don't know. But I do know a fella that has Lake Speed looking into it for his Hemi. Lake didn't know either but is investigating it.
  10. Pretty rare for any GDI motor to not display some fuel dilution. Has to do with the fact that cold it doesn't vaporize the fuel, it atomizes it and the silly practice of over rich cold starts with really late ignition timing. A practice used to get the cats up to temperature quicker. Burning fuel in them. If you lab used GC instead of a 'crackle test' I'd expect you would see a percent or so. Copper in Ecotec3 motors is not uncommon. Platform specific. Hemi's do this too. Pepper at 165K still showed about the same amount she did at 80K. I don't worry about it. She's nearing 200K and runs like top. Should have latest results some time this week. I don't know what oil you are using but shear down of the VM is absolutely possible in that short of time. What we considered a flaw a few decades ago in VM chemistry is now advertised as a 'Feature". One used to get enough viscosity driven fuel economy improvement into the 20 and 30 grade oils. ILSAC GF-6 and API SP requirements. It's the main reason I don't use them and vis up one grade when I am forced to. IMO using a better lab would be helpful. Ask Nick. @Black02Silverado. I use his lab and get good service.
  11. Bought mine at Walmart
  12. Black plastic grill treated with Cerakote. She sits outside 24/7/365
  13. I did the grill about 10 years ago with this product and it still looks new. It's some good stuff. Your headlight look really nice.
  14. Saw $2.72 all over the place today. On a trip to Iowa picked up some E85 at $1.89 Nearly a tank for 30 bucks.
  15. Saw $2.72 today!
  16. ZDP https://link.springer.com/article/10.1007/s11249-016-0706-7 At least read the discussion and conclusion.
  17. Don't see this every day Typically we see this curve only for neat oils with no VM's. They complicate things. This one is for a single weight with 'friction modifiers'. (ZDP, Boron, Moly etc. e.g.) No VM. Where do you think current design is placing OEM viscosity selection? Read up on GF-6B oils for a clue. Read up on the difference between GF4 to GF6 and ask how they get less friction from the same 100 C viscosity brackets? Explore the history of VM's for your answers. What are you relying on for wear control between the blue and green slopes? How does that work in extended drain intervals? Since your UOA will only tell you the presents of the element and not its chemical availability, how long is to long? What does your current observations of the whole of the industry and ring seal law suits tell you about this strategy? Trust me, I know what I'm doing? Tribologist are not power train engineers and power train engineers are not tribologist. Marketing people are neither and accounts haven't clue about any of it.
  18. Saw $2.73 today at a Kwik Star and a Casey's. I've kept a chart of price since I bought the Mitsubishi and the price is for Premium but the trend is flat although the swings are wild. Yellow is 24 point average and the red the linear average. Dead flat.
  19. 191,230 Mile Oil Service 10/14/2025 191,229 actual 3,750 mile nominal OCI. 120 days. Still honey on the stick at this distance. Improvement. No consumption. No detectable loss of fuel economy. 6 quarts Red Line HP Euro Series 5W40 4 Oz. Red Line Break-in additive 1 Purolator Pure One PL22500 filter Pulled sample for UOA. Adjusted Headlamps down.
  20. The Bills are up in 3 weeks and the only one ESPN has nearly even odds on. But we weren't supposed to loose to the Chargers either so....
  21. I took note of his comments that you can find a study to support every position or belief. I agree. He also says to do it right you have to TEST and then admits he is to lazy to do that. Well....a least he's honest. I like that. I'm not that lazy. I test. Oil Geek and this guy are in about 99 point agreement. And yet both walk around significant facts that only testing would reveal. Honestly, that is to be expected. Their coverage of generic and the advice would of necessity require it to be specific and that, again, would require testing. For example, his talk about the graphs showing viscosity v temperature walk around the fact that POA's response to cold is quite different from a mineral oil (Group II or III) with even PPD additives and as I've displayed before can be a grade or more different as the specification for qualification is a MAXIUM with no minimum. Here it is again. They both use words like 'Significant" when speaking of the differences in wear. That world implies a standard to judge 'significance' against. Slight of hand but it doesn't mean none, it means compared to THE standard and they leave us in the dark about what the value of THE is. In the Steinbeck Curves displayed the points plotted on that curve for oil grades were plotted to make the point he was making. They were not random. And it is the main reason that you can find a study to support any argument you wish to make. The actual placement of that point on that curve is unique to the example under discussion. Right down the driver as the driver controls the average and median LOAD applied of the test and over the life of the unit used in calculating the Hersey number. To know your particulars you have to instrument and test. Acquire data and LOOK. You can not make blanket statements about lubrication. I have two such studies underway right now for MY equipment.
  22. I can think of a few thousand reasons ($$$$) it isn't.
  23. Looks like the Funk is over! Lions are tough. But can we make up two games in the division?
  24. $2.88 is now cheapest and rare for 87 E-10
