Engine oil Motorex or OEM FORD

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

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.

On a side note, if anyone really wants to see what their oil change interval should be, just get an actual oil sample analysis done. Per the lab reports, I can get 8k miles on quality synthetics and still have a good safe margin for oil life.

Ford is telling me to change oil at my Focus every year or every 15000km (9300 miles)

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

I red-line 1st and 2nd gear when merging onto highways from the on-ramp. But then cruise at 100 kmph on the right lane. Gotta have fun when you can! Ensure that **oil** temps are good, not just the coolant.

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 have a 98 TDI with 269k and I had an 06 TDI with 131k. I have dumped the unfiltered engine oil after each change into the tanks of both cars since I've had them (Beetle, 98, got at 230,880 miles). They burn fine.
