Don't put R in the sump without a full rebuild and even then will it be OK for the gearbox?
they used to run R on racing engines back in the day!
but they were more frequently rebuilt back then and the oil is different to what it is today.
im only putting it into the fuel tank so i can get the smell, without using it in the engine. il probably only put 3/4 of a thimble full in every tank or whenever i remember
Indeed thayll make a nice paper weight as they're one of worst oil you can put in an engine, but the tin looks retro and cool
how is castrol R the worst oil to put in an engine?!?
and yeah, looks cool 8)
