I was looking at proactively changing my BTR Hydratrak oil as I don't know what's in there or how long its been in.
Incidentally the chassis manual suggest change at 500miles run in.
The CRS Chassis manual states a mobilube SHC 80w-140D API GL5
This seems to be an Australian blend and I cant find it in the UK.
I have asked mobil uk for the equivalent They have a HD 80-140, and some say SHELL SPIRAX S6 AXME 80W/140 is equivalanet
I have also seen a redline oil claiming to be API GL5 80-140 equivalent.
I was keen to know what others are using.
