I have been told that once you start useing synthetic oil you cant go back to regular
what do you guys think?

 

BullSit!

There once was a detergent/ non-detergent oil problem when switching but I don't know if they still sell that stuff

 

You can switch back no problem but why would you?

 

synthetic oil protects your motor better, lasts longer, is higher performance, and helps with your milage.

 

don't mix any oils or additives together for best performance and use SYNTHETIC oils ONLY.

every oil change if you wait til the very end where it doesn't have too much,,switch synthetic or regular it will not affect,,,if you DO mix through the tank,there start the problems,,,

 

Synthetic oil is just high refined regular oil with less natural contaminates like sulpher. These contaminates when mixed with combustion by products and water form acid. So with less acid, you have less oil changes. Unless you have a worn out engine with lots of blow-by, creating lots of friction creating by products in your oil. Which is the other reason for changing your oil, getting rid of damaging waste carbon that comes from the combustion process. I hope that makes sense.

 

A lot of people will give you bad advice when it comes to synthetic oil. Some of the advice here isn't too good either. You want to learn about oil. Spectro makes oils for powersports machines only. In my 25 years of driving. It is the best I have ever used. In my two stroke it is totally smokeless. Read this info and some other stuff on this site.

Polaris went to the 0w40 synthetic and recomends it because when the old 425 and 500s first came out they had cam trouble due to topend oiling.The synthetic cured it(when changed regularly).I would stay with a synthetic.

 

theres a reason they come factory w/ synthetic oil in them. if not they would use regual oil.
