Engine oil VALVOLINE or MOTUL

I only run Valvoline VR-1 40-wt in my air-cooled VWs

I tell you the stuff really works. My 2009 Matrix used to burn oil before I switched to Valvoline Restore and Protect.

i honestly have no way to prove if it works, but i started using it in my ‘98 corolla about 20k mi ago (known for burning oil due to flawed piston design) and have noticed a significantly lower oil consumption rate, which was almost 2qts every 5k down to less than half

I normally dont buy into stuff but my vette was burning oil, Id see a big cloud of blue smoke after I let off after every pull, few thousand miles of this stuff and I stopped seeing it.

That stuff ROCKS! Cured my stuck piston rings issue on my 201O Acura J37 engine.

It works. It’s a quality oil that I use in my daily 5.0 S550. Used in my 200k mile 2.0L turbo fusion and the first oil change was so gross. Blow by has gone done a lot.

I've used it for about 25k miles in my Camry with the 2AZ-FE engine (200k miles on it), it has the known issue with the piston rings being poorly engineered and seize up from excessive oil burning. I can personally confirm it has cleaned up my pistons, I haven't taken the engine apart so can't directly see the rings but oil consumption has reduced from 1 qt per 1k miles to now 1qt per 5k miles.

It sure does work, cleaning dipsticks and reducing oil burn has been my experience on several personal cars since starting a year ago. I bought an MDX burning almost 1 quart oil / 1k at 155k, now doesn't use a half quart every 3k now at 185k.

I used so many brands

- Motul : okay

Could be the oil and not any problem with the engine itself. In India, these engines come with Motul 7100 full synthetic oil. There have been some discussions on the 390Duke forums and on Reddit that the oil burning issue and high oil consumption is caused by using Motul 7100
