khunjeng - I'd like to check something with you.
Scenario:
Engine oil - Fuchs Titan Supersyn 5W-40 (just as good as Mobil 1 and costs pretty much the same).
Oil Filter - Ryco (I know you hate these and I will get genuine next time around)
The car is street driven and never sees the track. The car is not given a hard time. It just has the usual bolt on mods and aftermarket ECU.
I currently change my oil & filter at about every 5000km-6000km.
I've read previously that oil filters don't start working at their best till about 4,500km. So is it safe to say that changing my oil filter at 10,000km is ok?
In saying that can I extend my oil change intervals to 10,000km as well?
Another one - Motul MT90 can't be used in a viscous diff can it?
Thanks
