I know once you go synthetic you are not suppost to go back to normal oil, but is it possible to do this, if say you flushed the synthetic out with normal and then filled up with normal?

The reaosn I am asking is, because I want to try to use synthetic to maybe get my clutch from sticking, see if that helps and then if it doesn't to switch back to normal oil. Or if I got synthetic do I have to stay.

And last, what brands make ATV synthetic oil, becasue I heard you aren't suppost to use car oil because its not good for the clutches.

I used Torco full synthetic oil in my dirt bike because the previous owner used it from day 1. I asked a mechanic the same question you're asking and he told me unless you completely flush out the engine and gear box, you may gum it up by mixing - running 4 or 5 litres (sorry, Canuck here) of normal oil won't clean out the synthetic. That being said, the machine ran synthetic for 10 years. I doubt you'd have that issue if you ran it for a couple of hours with synthetic. I'd still probably have it flushed though. BTW, some synthetics are heavier and actually cause clutches to stick. At least it did with my bike.

 

For a minute there I thought this was an april fools thread. Stop worrying and run whatever oil you want.

 

You can switch from syn to normal oil and back and forth as many times as you want it won't make any difference. when running syn in your quad use the stuff ment for quads and not for cars.

 

no kidding eh

i use what ever oil i can find laying around and theres no problems

0-w40 10-3w0 10-w40 20-w50
synthetic non synthetic

i would never buy the honda oil, its like 11 for a liter, i buy the quaker state for 3 $

 

One, of you guys were saying something about running w/e oil, its not the fact I want to switch, its more so will it help out with the clutch.

HughJazz is correct. Oil is oil, it all made from the same base product. Some of the base crude oil is of a sweeter quality but that is as far as it goes. The difference between synthetic and regular oil is the amount of refining and extra additives in the final blend. Not only can you change back and fourth, you can mix it with no adverse affects.
What needs to be considered most about oil selection is if the oil meets the manufactures specifications. Is it the right grade, does it have the right API spec. For example, in 35 to 115 degree temps a Grizzly 660 specs SAE 20w40 API SE, SF, SH or higher. Also not recommend for use is oil listed as “energy conserving”.
