Re: questions about oil
The bottle says 50:1, but the engine manuals usually say 25:1. I don't have a manual for my new motor, but I bought it on eBay and its a replacement motor, not the whole kit. The grubee manual is the one I have. Let's not get into a whole debate about the accuracy of the manual, so far 99% of the info in the manual has proven accurate to me. Also, someone whose knowledge and experience I greatly respect has told me to always follow the engine manual. The difference between 25:1 and 32:1 is about an ounce of oil. I don't think an extra ounce of oil is going to kill my engine. I do regular maintenance, don't ride too hard, and never keep the throttle at one position while riding.
