vs
Engine oil Motorex or PETRONAS
In my Shiver 750, Motul or Motorex every 3,500 miles were required to keep neutral findable when you want it and hidden when you don’t. False or impossible-to-find neutrals were a sign that it was time for an oil change.
Pros: findable neutral
Cons: impossible-to-find neutrals
Mileage: 3500 km
Use an oil designed for a wet clutch, like this [motorex 15w50]
Pros: designed for wet clutch
Petronas Syntium 5w 30 on a mercedes and audi a6. No complaints at all, and good price
Pros: good price, no complaints
Vehicle:

Well I decided to try Motorex on my F800 GS, bought the 4T Top Speed full synthetic, in 15W50, boy I cant help it but recommend this oil, the gearbox is so smooth and silky.
Pros: smooth and silky gearbox
Vehicle:
BMW
The 5W30 full synthetic engine oil works the best for a wide spectrum. Its working temperature range is practical for daily use and it costs less than 5W40.
Pros: practical for daily use
Cons: costs less than 5W40
Vehicle:
Mercedes
My giulietta 1.4 MA is still reliable at 130k km. Never had any problems with engine always used recommended petronas oil. Had to rebuild my turbo once (at 120k km) it had very little play that made my car burn some oil.
Pros: reliable, good engine
Cons: turbo rebuild needed
Vehicle:
Alfa Romeo Giulietta
Mileage: 130000 km
I use motorex 30W in the air (or coil) side. The motorex is great stuff
Pros: great stuff
Motorex 60:1 piston and rings go 180 hours with out issue, could go longer but i change it every winter, powervalve has yet to need to be seriously cleaned in 3 pistons.
Pros: piston rings last long
I went with the motorex recommended oil. Worked great.
Pros: worked great
I paid $90 bucks for a full oil change the first time, using motorex. now for my 2nd change, she's getting Rotella T6 because it's cheaper. I put on too many miles a month to shell out $90 bucks every 3k miles.
Pros: null
Cons: expensive oil change
