Yamalube, semi-syn, full-syn, I would like to know. Yea, I know the process, break it in on factory oil and one or two oil changes with yamaha spec oil, did that, now wondering what you guys are running. I know my 4-strokes and had good luck with semi- syn Bel-Ray 20/50, 10/40, in my other rides, plan on running the same in my Raptor. Don't feel full-syn is nessesary because I service my toys more often than I service my wife (Sorry, honey). I don't mind spending a little more for Yamaha spec filters either.

Just curious whats been working, or not working, for everyone else. Call me crazy, but my goal with my Raptor is ,for as long as possible, to keep from putting my wrenches on any part of the engine for anything other than normal service and minor tuning. I'm sure, from what I've experienced so far, that will not be a problem.

 

I change my oil and filter after every ride. I ride at Glamis and Dumont and go for three or four days at a time. I usually put about 100 miles on it every trip. I have an odometer. John, the owner and head mechanic of Mission Yamaha said to run Yamalube only and the engine should last a very long time. Mission Yanaha has a good reputation for engine building, and John is well known. Synthetic oil is great in that it draws itself to heat but it tends to make clutches slip since they get so hot. Synthetic just goes right to it and makes it slip.

 

Sonic, after break in I used the Yamalube semi-synthetic. Last couple of oil changes, I have used Maxima 15w50 full synthetic...probably overkill...but overkill is good is'nt it?

 

Yamaha , yamalube 20/40

recomended in manual

 

I use Honda HP4 20-50w.In my raptor and my yz400
that I race.Never had any problems. Only cause a local Honda dealer gives me a discount. And my local Yamaha dealer SUCKS!!!!!!!!!!!!!!!!!!!!!!!!

 

penzoil 20W50. those high priced oils are a scam. change it more often with "regular" oil and you have nothing to worry about.
