First oil change time. Should I use synthetic or not? I have some Castrol Syntec 10W-40 Full Synthetic oil.I also have some HP4 10W-40 Honda Synthetic blend oil.I just need a bit of advice PLEASE. Thanks Mike [img]i/expressions/face-icon-small-confused.gif[/img]

 

If you don't have performance clutch springs, then don't run synthetic. It can cause clutch slippage.

 

OK, so I should'nt use synthetics. Is this Honda blend OK ? What do you recomend I use? Thanks, Mike

 

If you have hp4, I would run it. Thats good stuff!!!!

 

If you get stiff springs then run it. Otherwise I would stick with a petroleum based oil. Spectro(not gold) is a good choice, or any others that are designed for wet clutches without friction inhibitors.

 

Mobile 1 contains no friction inhibators. Been running it in my BIG street bikes for a combined milage of 75,000. Never had a problem. Would a quad be any different? I'm thinking no. Am I wrong?

 

I run the BRP XPS fully synthetic. It was rated as one of the best oils to use. Also, Castrol makes BRP's oil. I use fully synthetic in all my toys. Quad, sled, Harley, mustang. I wouldn't use anything but.

 

Im for the HP4 too!!

 

Been using Mobil 1 in everything. Mx4t has no friction modifiers and you can really tell it's some fine oil when you start it up on one of them 10 degree mornings.[img]i/expressions/face-icon-small-happy.gif[/img]

 

The best Synthetic is Redline.

"If you don't have performance clutch springs, then don't run synthetic. It can cause clutch slippage." WRONG


Not all Synthetic oil are equal. Only those Synthetic oils that have added friction modifiers should not be used with wet clutches. Redline has no friction modifiers. Contact redline's tech line and they can give you all the specifics.

Now as far as switching from dyno oil to Synthetic it doesn't matter when you do it. Any quality Synthetic oil will blend with dyno oil without any issues. Hell they even make a blend between the two. Now with that said it is NOT recommend to switch from Synthetic back to dyno oil, so once you start you should stay with Synthetic.......
