Engine oil VALVOLINE or RAVENOL

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!

Run valveoline restore and protect for 3000 miles. Add engine oil flush before eat oil change according to their instructions repeat 4 times or more. After that continue to run valvoline restore and protect until the engine dies

Edit: dies from old age at 500k miles

8,000 fall through spring, 6,000 for summer, running full Valvoline full synthetic.

Don't know how many miles is on this car but these are notorious oil burners. It's a long shot buy you might try running Valvoline Restore & Protect oil.

If you do research oil analysts here in this sub, Valvoline comes out the best.

Using high mileage oil (additives to make gaskets swell just a tad bit), used to burn almost a quart between 5k miles but now it's maybe half a quart.

Looks real good. Valvoline R&P is in mine now.

Currently have Ravenol EFE 0w-16 in and have use Pennzoil Platinum, Eneos, and Idemitsu IFG7. I noticed bit of emulsified oil on the dipstick especially when I run in EV mode mostly. So definitely get it out on the highway on a daily basis if possible and get a used oil analysis. I have had 3 done and all three showed various 0w-16 oils shear down out of grade and their Flashpoints decrease.

I used that once years ago in my 2011 Limited on Stage 2. What a waste of money.
