Adding oil to the fuel tank(premix) takes away any risk of damage to the Apex seals etc due to the metering system failing ....many RES have failed due to this .....Two stroke oil will provide this added protection with easy mix in the fuel tank ......Again check your metering tank usage ......safe to say any quality oil of the correct grade will offer total protection for both sump and metering oil use .....

Combustion temperatures are going to be similar in all engines, and the oil should be light enough to burn off leaving little residue after performing it's primary function of dissipating heat. When I was racing, and using Castrol, a strip down after each race was mandatory to de gunk the internals, especially valves. I'm new to Wankels but, having read a couple of technocal bulletins, it seems they are designed to burn oil as part of the rotor cooling and I would think you' d want a lubricant that would leave very little or no trace of itself. If Suzuki recommend Catrol it probably is just the brand and they are not talking about the old castor bean blend but a conventional grade petroleum based oil. What did Mazda and NSU recommend?

What did Mazda recommend? Dead Dino oil.*

Wayne said, Suzuki was cautious re the engine and the. I agree, very cautious and conservative in estimating engine life, in my opinion.
I was told back then by my friend who knew, that he felt Suzuki would probably not put near the time in testing and development in any future bike and that includes the testing of oil and fuel deposits on the engine seals and spark plugs. Suzuki had their patent on the seals and did extensive testing to insure long life.
I am pretty sure Shell made the Suzuki branded RE5 Oil and I don't hold Shell stock as far as I know.
I remember one of Suzukis advertising illustration that seemed to illustrate the seals were near their wear limit at 50,000 miles. I have proven 150,000 miles is a reasonable expectation of the propers service life with reasonable care and maintenance and the recommended oil. Tim
