Engine oil Motorex or FUCHS
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
At the end of the day, pretty much anything in spec will work fine.
That being said, I did a bunch of research for my V85 and determined that Motorex Cross-Power does the best in high demand applications. Air cooled engines can have a really wide temp range. That's what I use.
Pros: best in high demand
I can whole heartedly recommend Fuchs Silkolene oils, it actually quieted down my sv compared to Motul.
Pros: quieter than Motul
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
It works great, maybe a bit expensive. I've run used oil analysis and change it 3-4k miles based on aluminum wear. I don't see a reason to use something else.
Pros: works great
Cons: a bit expensive
I use Motorex semi-synthetic 4t in all of my KTM's over the years in a 15w50 weight. It has never been an issue. I have used Motul 5100 and 7100 in other bikes before, and I prefer the 7100 over the 5100. It feels like the bikes perform better when the temps rise and I'm really riding them hard.
Pros: bikes perform better
Oil that I used is Fuchs
It takes a “synthetic blend” of motorex 15W50 oil. And uhh yeah works good I guess, don’t have to change it too often, and as far as performance goes, it doesn’t really matter because I’m on restricted power anyways so yeah ????♂️
Pros: works good
Cons: restricted power
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
