I still have my amain fuel here that i ran when my rear bearing falied in my go 5 port so i am going to do a few tests.. That fuel of mine is only a couple of months old too btw
And in regards to your post re tuning, Bearings do not fail before a piston/ sleeve assy will fail if your engine is to lean.... Sorry!

No problem, I respect all opinions. My posts are just opinions too. From my experience corrosion will not happen after using after run oil. I put after run in after my main while the engine is still warm.
And I have also had a rear bearing failure tuning a Max Power engine. I was not driving just tuning so I had no feel for the engine when it over heated. The engine came in for fuel and I noticed it was wayy too hot so we shut it down but it was too late. The rear bearing failed and ruined the engine.
