However, if you are talking about Redline Racing Oil (2t), that is not a product for the non racer. And especially not for lawn equipment.
It promotes corrosion of internal brass carb parts and does not prevent internal engine corrosion (remember, most 2 stroke oils do a great job of preventing internal engine corrosion). I actually had a ryobi fail on this stuff! Took it apart and guess what I found? RUST!
Maybe it's great oil for shifter karts when the engines are fuel are changed regularly.
EDIT: from another RRO user: Redline: This was a strange oil. The piston and cylinder looked good, with minor shiny spots but no scuffing, and everything was reasonably clean and well-lubed. But this oil actually left surface rust on the crank wheels, and tarnished the carb brass. It also had a tendency to gum up the carb jets for some reason. How a metal surface can be both oily and have rust on it is beyond me, but clearly this oil lacks any proper corrosion-inhibitors, and it must have very high levels of esters that give it a strong hygroscopic effect. I would never use it again, nor could I recommend it.
A quick google search of redline racing oil corrosion brings up a few users who had the classic corrosion problem.
My Husky dirt bike also failed a crank on RRO. I kept the crank around to show the rust to others. As they knew I rode regularly.
Thanks for the info. What I've got isn't actually the racing oil, it's the regular 2 cycle Smokeless Oil. Here's the link to the product on Redline's site:
