I have a 2012 gmc terrain 2.4l currently at 202k. I’ve used Lucas oil and restore and protect Valvoline oil the last 50k. Still runs like a gem with 177-182-179-175 compression cylinders 1-4. Used to be 155-149-144-168 before I started using both these oils
Pros: runs like a gem
Mileage: 202000 km
I exclusively have used Lucas oil for my sportster motor for 5 years. The bottle looks cool, that's it. Full synthetic oil, no frills, cheap, and easy to get.
Pros: cheap, easy to get
Cons: no frills
I have an 2007 A4 2.0T base. I bought the car with 120k miles on it in 02/19. Yesterday I hit the 224k miles on it. She's my daily driver, over the years I have changed/did the engine oil every 4k miles, car filters all over, wheel alignment, tires, brake pads, rotors, and the battery. Nock on the wood, my baby have been taking car of me. I'm actually surprised that this model is solid af.
Pros: model is solid af
Vehicle:
Audi A4
Mileage: 360000 km

Ive been using 5w40 for 100k miles and my engine is happy as can be. It actually is noticeably smoother with thicker weight
Pros: smoother with thicker weight

Audi A4

Lucas OS works great. It's some amazing stuff, BUT. Do not go over your oil change intervals. Once the Lucas additive starts breaking down it turns to a nasty varnish. Went 7k using synthetic amsoil z-rod and Lucas OS, on a new rebuilt 4.0l. Lost a lifter and ate up the cam lobe.
Pros: amazing stuff
Cons: turns to nasty varnish
Mileage: 7000 km
That looks like you dropped a valve. Yes Lucy’s oil will help. It will lubricate the chamber so you can take out all the pieces.
Pros: will lubricate the chamber
My mechanic added a bunch of Lucas to the oil, which he said might at least quiet it down, and it did. It's quieter now, but I can still hear it at idle.
Pros: quieter engine knock
Cons: still audible at idle
Had a Q5 and it was a money pit. Oil Consumption got so bad I was putting in a quart every 400 miles.
Cons: oil consumption bad
Vehicle:
Audi Q5
