This has no doubt been discussed in the past, but what's the current thinking on the best engine oil to use in a K Series? Mine is a 135 model.
Many thanks,

K Series Engine Oil
Re: K Series Engine Oil
I always used Millers 10/40 fully synthetic in my Elise and always worked well. But look up the fascinating analysis by David on engine oil performance during his race season, food for thought.
Currently have Millers 10/50 in my VHPD.

I have always used this stuff in my S1 135; Fuchs Titan Race Pro S 10W-50 Ester Synthetic Engine Oil

Re: K Series Engine Oil
As others have said, something fully synthetic and 10/50 is ideal, though remember the engine is from a shopping trolley, not a highly tuned race machine.

Mobil 1 0w/40 was my lube of choice when I changed my own oil.
