mixing semi and fully synth oil?

[druist]

I know you arent supposed to mix mineral oil premix in your tank with synthetics but does it matter if you have some fully synth in there (half tank 3% rock oil red stuff) then put the rock oil green semi in?

Ive mixed semi and fully synthetic putoline in the RB and muggy and had no problems with either.

no problems at all in mixing semi; fully synth or mineral. Back in the good old 1960's any old oil was used in the dispensers with no ill effect.

I think some people may be getting the mixing of CRANKCASE oil confused with 2T oil.

Hi Chris....i do believe the only oil we couln`t mix in the `60`s was the Castrol "R" what the racers used, as it is a vegetable oil.....do you remember that gorgeous smell!!......i haven`t seen or heard of it for years.......
