My stepson mixed his oil 100:1 while I was away from home per the instuctions of A NAPA auto worker. He ran two gallons thru it at this ratio. Should I replace my rings or just wait to see what happens?
100:1
- Thread starter scottw419
- Start date
as long as it runs fine now I wouldnt worry about it... Youll be able to tell if its screwed up by running it
A coupla gallons may not have done any damage, mix 32:1 and hope for the best.
Make a point of getting in that NAPA workers face with the bill if anything is wrong.

Why would he do that?
If the kids old enough to ride it he should be smart enough to atleast mix the proper amount of gas?And if he isnt then he should have been taught to and explained the rhyme and reasons.At the very least im 100% sure the kid can operate a computer and googled the premix ratio of a blaster what maybe 15-20 secs of his time to confirm he was doing it correctly?
I dont see why its the napa guys fault???Instead of probably going to jail over some dumb sh*t school your kid on the basics with his machine at the very minimum how to tune it up change oil and premix.
Hell ken's got a video of how to do it you dont get much easier than monkey see monkey do.
Some kids are gullible and will take advice from their elders especially if they sport qualifications, that auto guy gave him the wrong information, he should have known better.
Staying out of the whole 'who was at fault' debate, I'll just say this: CARNZ is right. If you starve a 2-stroke engine of oil, you can forget about replacing JUST the rings. There won't be much piston ring left by the time the engine comes to a stop.
When you scorch a 2-stroke due to a lack of oil, it will either seized up solid, or the rings will have melted into the piston on the exhaust side, and you'll have metal transfer to the cylinder wall around the exhaust port. (Score marks). If this happened to the OP's stepson's Blaster, it would be obvious. The engine would either be locked up tight, or it would kick over 'dryly' with the burnt piston/ring mess dragging the cylinder wall.
Point is, if it is still running and the engine isn't hard to start cold, it survived and you got lucky. Like others have said, certain 2-stroke oils actually call for a leaner mix and they are designed to run this way. AMSOIL Saber is a 100:1 oil straight from the bottle, and at least one member on here has had luck racing with it (I don't remember his name, but he hasn't been on in awhile.) I run AMSOIL Interceptor at the recommended 50:1 ratio in my Blaster and have had nothing but the best results. My engine runs fine, throttle response is snappier, and I have a bit more usable power than when running pre-mix at 32:1. Bottom line: Follow the directions on the oil bottle.

Haha, man if it wasnt for here i would believe a napa worker also i give the kid props for atleast asking questions to make sure its right.
If it still has good compression i wouldnt do anything. If the compression is weaker then id put a set of reeds in it.
