Rating 4.5

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 paid $67 for 4 qts of lucas full synthetic oil and a filter on Amazon and just grabbed an O ring from harley. Harley's oil is fucking garbage. Lucas, Amsoil, Motul & Mobil 1 full synthetic are all damn fine products.

Pros: damn fine products
Cons: Harley's oil is garbage

Personally I run Lucas oil in mine, not just my current zzr600, but even my older vintage bikes when I had them. It isn’t crazy expensive and is high quality.

Pros: high quality, not expensive

I run Lucas in all 3 holes and my bike has been cooler, less noise and shifts smoother than it did when I got it and it had Harley fluids in it.

Pros: cooler, less noise

Rating 3.0

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

  • Exhaust smoke:
Rating 1.0

I used the middle one on an old 200,000KM Porsche Cayman S that was burning oil. It made it worse, smoke started coming out of the engine when the oil cap was off and I felt like the engine would soon die.

Cons: made it worse, smoke
Vehicle: Porsche Cayman
Mileage: 200000 km
