Engine oil VALVOLINE or Shell

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

The interesting part is that the T6 was used to tow a camper from Indiana to the Oregon coast where we are now. It’s interesting to see the viscosity, flashpoint and Moly are higher in the T6 even after towing through the mountains and more miles on the change.

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.

I'm trying out Valvoline Restore & Protect right now. I only ran oem Idemitsu before but started to have oil consumption issues with that oil the last two winters so I decided to switch.

I tried Rotella when I first had my truck but it kept smelling like it was burning so I went to Valvoline Full Synthetic since it’s certified for Cummins.
