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.

Use an oil designed for a wet clutch, like this [motorex 15w50]

Petronas Syntium 5w 30 on a mercedes and audi a6. No complaints at all, and good price

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.

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.

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.

I use motorex 30W in the air (or coil) side. The motorex is 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.

I went with the motorex recommended oil. 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.
