Mobil MOTORSPORT FORMULA
Have 10 litres of 0w40 mobil and 10 litres of 10w60 MOTORSPORT FORMULA mobil, sitting in the garage ready for another oil change this weekend.
I wanted to use the 10w60 to do a complete oil change and hopefully reduce some of the oil burning every month from me driving it hard. A few on the forum metion using it? Most BMW M series seem to use it?
If it I mix both together will it effectively be 5w50?
thanks
I drive hard for long periods and get the engine hot on fire.......so hot that the fuel returning to the tank is steaming vapours from the fuel cap after a good 20 min beating.
What I am trying to do, is match up the hard beating over 100k on the engine with an oil that is suitable against any increases in any wear tolerances.
I was stupidly using 5w30 for a while ......(a 25 litre barrel cost less than 8 litres of mobil) and was using 1 litre every 1k, switched to 0w40 and its less than half a litre every 1k which is exceptable.
But there are some on here that use no oil. When I beat the crap out of the car, the engine temps increase and to the point when the oil thins out = oil consumption................................ which I know is alot harder to do with the 10w60.
cheers

when i first got my car it was using abt 1 ltr every 5000 miles, but then the oil cooler split, had that replaced and the breather leak re-sealed and it hasnt asked for no oil since its service abt 7K back.
thanks man,,,, dont see any oil, car is parked same position everytime...
will have a check though, wheres the location of the cooler, in the wheel arch?

I visted a local shop and purchased Mobil SuperSyn 5W-50 Rally Formula instead and did the oil change a fews days ago. Filled it to 8.5 litres and have beat on the car hard doing over three tanks of fuel/approx 300miles ....... 100mph+.
result still 8.5 litres showing.
next changing plugs later this week for Bosch FR-6-MPP-332

Its been a few months and no problems at all. I just let the car warm up a bit before i drive it hard -- good idea no matter what oil you use.

thanks,
I thought the same thing, but the area around the plugs is bone dry.
I think its oil left over oil from the leaking rocker gaskets that I replaced a while back.





I ended up replacing mine with standard dealer items which are NGK Iradium (resister based ones) BrabusK8 can get a good discount (mbclub) if you ever need service items. about 40% off.
I ended up replacing all the ignition wires too, got them all from Bosch for £140, dealer wanted £460! and they are exactly the same thing!
