Very difficult for base oil stocks to meet the new API SP specification that applies to 2017 and later engines. A few engines can take a dino synthetic blend if the viscosity specs are high enough. When it comes to a 0W-XX motor oil it takes synthetic oil to meed the API SP specification. Any motor oil for a gas engine that meets this spec which is shown on the container, is going to be as good as any other motor oil despite all the advertising from people like those at Amsoil.

Anyone's thoughts on using synthetic vs Fossil fuel old fashioned oil?

How does engines accept this? Obvious modifications to the engine I guess? Im not a mechanic.

I want the best for the engine and dont want to cheapen the life because of the cost  3x per year to change the oil.

Also I always feel like getting the oil changed more often is better. Used to be every 3 months but now its every 5 months? 

I just bought a Chevy Silverado 1500

But even in My Ford Explorer I had they said I can do it every 5 months. Seems to long to wait to me. 

 

Thoughts 

 

Thanks

Nothing new uses conventional oil.  They leave the factory with synthetic.  Been this way over 10 years now in GM land.  

 

There are no requirements to change oils on older stuff either necessarily unless its a really old engine that uses older seal technology.  So if you were say driving an all original 1970 Chevelle that had all its original seals in it, its "possible" that newer oils could be more aggressive to those old seals.

Old post. I get it. :rolleyes:

 

Hum....API SP as a benchmark?  Okay, if that benchmark is the lowest the bar can be set. Dexos1Gen3 is only about a half a rung higher. 😬

 

Compare Castrol Edge Euro 5W30K with say Costco Kirkland Signature 5W30 FS. Know what you won't find on the bottle of Kirkland that on a bottle of Castrol? 

 

  • ACEA C3
  • API SP
  • BMW Longlife-04
  • MB-Approval 229.31/ 229.51/ 229.52
  • Porsche C30
  • Renault RN 0700 / RN 0710
  • VW 504.00/ 507 00
  • Suitable for use on the following specifications: VW 505 00/505 01

Look!

The problem with common sense is it isn't commonly used. 

 

API SP spec for HTHS is? 2.6 cSt

And for Porsche C30? 3.5 cSt

And for API SAE30/*W30 it is 2.9 cSt. 

Ever hear of the Stribeck? The Hersey number? And idea what they MEAN? I'm not explaining it again. :idiot:

 

SP as the latest version of the API should be a 10 then by that disclaimer on oxidative thickening and LSPI protection. Guess what. It isn't. Guess what is? Porsche C30. 

 

READ THE WORDS CURRENT REQUIREMENTS and pause long enough to let common sense take over. Requirements are set by the ASTM standard test RESULTS not the organizations or OEM's specifications. It is the SPEC that is not to be compared. The results most certainly can be. 

 

Do as you please but please THINK. Why would an oil meet the DEXOS1Gen3 or Dexos2 and miss Porsche C30 or VW 504./ 507. Ever see it the other way around? 😏 I'll pause while you search high and low for your blue unicorn. 

 

 

***********************************

 

Now that you've failed to produce an example, ask which organization has the higher standard. I give a sh*t about the OEM specification. They fail me every time. RESULTS matter. The tool compares results. The disclaimer is just what it says it is. A legal dodge.

The Effect of Oil Drain Interval on Valvetrain Friction and Wear

 

Excerpt

Quote

As in the previous study, the results showed that the aged engine oils provide lower friction and much improved wear protection capability. These improvements were observed as early as the 3000 mile drain interval and continued to the 15000 mile drain interval. The composition of tribochemical films formed on the surface with the 3000 mile drain interval is similar to that formed with the 12000 mile drain interval as seen before. These findings could be an enabler for achieving longer drain interval although several other factors must to be considered.

Every engine oil that you can purchase as a DEXOS, SP API or ILSAC engine oil is essentially GRP III based in some form.  Very few engine oils are GRP I or GRP II any more, they usually have at least a GRP II+ base and the additives are all synthetic.  SO the term synthetic means nothing any more.  To find a majority based GRP 4 or V based oil there are very few.  Renewable Lubricants Inc. (RLI)   Redline  Amsoil, Mobil 1, Torco, the brand from Chicago area that I have not tried that Grumpy and others have tried.   RLI is probably the most advanced and they use hybridzied veggie bases. Made in Ohio buy a farm family funded for years by agri chem biz.   I am trying a GRP II + with very little GRP III engine oil with no ZDTP from Chevron, DELO 600 10w30 in my 2.7 Turbo. Second oil change has cut my oil usage by 50% its seems.   That's probably as close to non synthetic you can get.

The operative phrase. That paper is focused on one variable and doesn’t consider any “other factors” even though they are important in the big picture. Like…can the oil keep the rings clean over such a long interval?

Could have, would have, should have and a dime won't get you a cuppa coffee. 

 

Most Oil shears down. It's the nature of Most VII's so yea, lower friction. And what does Stribeck tell us?  Tells us if that number does not support the surface finish parts that are not supposed to touch will. So I'm calling :bs:on a limited three vehicle study that has not be peer reviewed and specifics held in reserve. 

 

Besides, this looks AI generated. What kind of grammar is that fragment?? :rollin:

 

 One true thought. There are other things to consider. :idiot:

      seat base height *lowering* (base 40/20/40 seat, 2026 1500 WT std cab)

      By bwiese · Posted

      Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose

      I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Dave's Auto (custom engine builder) tear down of L8T

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
