Engine oil VALVOLINE or AMSOIL

I change the oil using Valvoline for the very first time. I pulled a valve cover in the next oil change and was shocked again! The heads were completely void of sludge! That’s when I became a dedicated Valvoline user and have used it ever since. I run it in everything from Porsches, Corvettes, I use the VR1 in my flat tapped engines and have never had a problem in well over 50 years. Just change the oil and filter every 3k miles or so and the inside of the engine will be clean as new.

I would do several short interval (like 1k honestly) with valvoline restore and protect.

I used Amsoil when I did mine. The squeeze bags they have make changing the fluid a lot easier and it's good oil.

Change your oil with Valvoline restore Cummins oil I think I used 10w30. It will help... I had a a4 with 130k miles and I did this 4 times it cut my consumption down to a minimal amount

Same issue, same engine. Switch to specifically Valvoline protect and restore 5w30, run a bottle of Berrymans B12 cleaner thru the gas tank before your oil change. I did this and saw improvements.

Could be a spark plug, ignition coil, injector or low compression.

Valvoline restore and protect is all that you can do. Best motor oil out there.

VALVOLINE RESTORE AND PROTECT AND SHORTEN OIL CHANGE INTERVAL! It will fix it!

I have amsoil in mine. I went 7500 once. Im sure anyone can go 10k with amsoil but it will be dark oil when u change it out lol

Absolutely Liqumoly!

Please never put Amsoil in a Volkswagen they under rate their viscosity/ wt ratings and the only time I used their oil I ended up spinning a rod bearing in my first R32
