Engine oil FUCHS or Lucas
I run Fuchs Titan Truck 15w40 in my Cummins 6BT, engine was rebuilt about 50,000ks ago, seems to go alright with this oil
Pros: seems to go alright
Mileage: 50000 km
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 can whole heartedly recommend Fuchs Silkolene oils, it actually quieted down my sv compared to Motul.
Pros: quieter than Motul
I like the Lucas ones personally.
Pros: user likes it
Am bagat si eu Fuchs intr-un 3.0tdi si in romania 1L e 60 de lei cam asa dar pe [Ebay.de](http://Ebay.de) e 35 de lei litrul la fel si Aral, ciudat de ieftin. Motorul merge cam cu 10'C mai putin la ulri fata de castrol(se ducea si la 119'C pe autostrada)
Pros: Motorul merge mai putin
Cons: ulei scump in Romania
4.5 L is the Ideal for Mazda 6 2.5 non turbo, I'm from the same country as you. I'm using fuchs titan 5w30 for two years and I recommend you do the same, I noticed quieter engine.
Pros: quieter engine
Vehicle:
Mazda 6
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
Eu stau pe fuchs la 1.5 dci cu norma 0720. Nici nu se compara cu motul, pe mine m-a lasat rece
Pros: norma 0720
Cons: lasat rece
