Will Mobil & SOPUS Develop R&P Equivalent ?

[4WD]

Just a guess but I think HPL could remove piston deposits based on @OVERKILL finding carbon after using Mobil 1, which at first I did not believe (not that I didn't believe OVERKILL but that Mobil 1 left stuff behind).

I think when Valvoline is saying no other oil can do this, it's based on the dry off shelf oils. Dry as in little ester/solvency. If HPL has as much AN/Ester as some say then its certainly possible HPL could remove existing piston deposits over time. Amsoil SS too.

But did not happen on my 5.3L with either product behind M1.
Perhaps engines have a greater role …

Yeah, the HEMI isn't the cleanest running engine, that's why it has 16 spark plugs, lol.

On the Canadian Mobil 1 website it does say that M1 EP HM can remove existing build up. Here’s a screenshot of it:

The ability to remove sludge is different than the R&P ability to remove carbon (much harder to remove carbon) .

I know that, but others here have been asking about what oils claim to remove sludge

I am sure the EPA would disagree with what you are saying. The Cat Converters take care of everything. LOL

I have never seen any evidence olive oil is not a great lubricant. It may be superior. Italian race cars used olive oil exclusively in the 1930s before they switched to inferior dinosaur oil for cost savings. Makes the exhaust smell nice too. Olive oil cleans out arteries, makes sense it cleans up pistons too. With a good supply of olive trees, an olive press, and a diesel Mercedes, there is no need to buy lubricant or fuel from evil corporations who only want your money.

My dog got into a bowl of olive oil we set out on the table. It suffered from HSBE. Hoping the new spec olive oils solve the high speed bowel evacuation issues.

Or, just avoid cafe oil weights, lower the oci, and just about all synthetics will run clean over the lifespan. Its the small sumps, gdi, turbocharged and extended recommended intervals that got all the craze for oils that clean up gunk. Buy a better oil filter, get that engine up to temperature which could take longer than twenty minutes on a highway, use detergent fuel, check and top off weekly, and change your coolant and transmission fluids every 30k.
