Engine oil Pentosin or Lucas
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 use Pentosin Pento HP II fully synthetic Euro Spec 5w-40 oil (made by Fuchs Oil in Germany). According to test data I have read it is a much better oil than the Mobil 1 oil. I believe that the 5w-40 oil provides greater protection against oil vaporization, as the OM642 can run at elevated temperatures leading to high oil temperatures, which tends to break down the oil sooner.
Pros: better than Mobil 1, greater protection, resists vaporization
I like the Lucas ones personally.
Pros: user likes it
After talking to a European mechanic. He said u need Germany oil for a German car. American oil is trash bc of the EPA regulations. He recommended Pentosin. The tick tock went away and I've been using it every oil change
Pros: tick tock went away
Vehicle:
BMW
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
I used lucas in my honda and will use it on my next change for harley
Pros: will use again
Vehicle:
Honda
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
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
