Expensive but worth it
My ‘08 5.7 Sequoia has 184,000 miles and was starting to have a slightly noisy lifter tick. Added this every oil change 3 oil changes ago and wow - what a difference. My 9 year old daughter asked at a spot light “daddy, is the truck on?”. It made the truck super quiet and smooth. I added the whole can after a full oil job. Not worried about measuring the nats eye with oil capacity.

This works
Have been using Liquimoly in all of my cars for years across many brands and the stuff works. There’s a review here blaming Liquimoly for an engine failure they had in a Hemi but that has nothing to do with this product. That failure is a well known Hemi issue with the MDS system. Something Mopar needs to recall. Not liquimoly. I wrote this review in defense of this product.

Great oil additive
This stuff is a great additive for keeping the oil viscosity for times you may need your oil to last longer!

Protects 6.7 Powerstroke engines
Excellent product. Add to engine oil in F350 Platinum. It is amazing. Expensive but cheaper to care for the engine than repair it. I add every oil change.
