Title: C15 oil
Post by: TIGERJ on 25 September, 2017, 13:10:12
Now engine has run a few hundred miles thinking about oil change.
So probably use 20/50 again ?
Also
I think I read in Rupert Ratio gear box oil recommend 90s grade
Anyone used this.
Regards

I use 50 grade in both engine and gearbox with no problems, interested to see if this is normal practice
