What Oil?

26 posts in this topic

Up until now I have been running Yamalube in my 07 WR450.

What oil are you guys running and happy with?

I was thinking of going with yamalube 4R 10W-50 but wanted to see what some of the people with four stroke knowledge thought.

Thanks in advance.

I was running synthetic, but when I got my Rekluse clutch, Rekluse recommended Rotella oil. Its available from Wally World and cheap. I replace my oil every 400 miles and don't push the bike that hard, so don't see any point in running any of the performance oils.

Plenty of threads on this topic, so use the search engine.

Second that for the Rotella. However, I go no more than 200 miles on my 07 and 300 miles on my 99 between changes.

I run Amsoil full synthetic in mine with a Rekluse and have no issues. I replace the oil every 3 rides or 150 miles, whichever comes first...SC

I'm on about the same service schedule as Clarke4131 , but I have been using OPTI-4 since I went 4 stroke in 2002 and I have been very happy with it. Previous to that I used OPTI-2 for over 10 years in my 2 strokes with great success. I still use it in my chain saw and weed whacker. :) WR Dave

I also use Amsoil in everything I own! economicle product an when you look at very econical. In my truck I have ran it since new 25,000 mile's on one oil an one filter. With over 200,000 miles an 10 oil changes You do the math for saving's

Oh yeah its about 50.00 for a compleat oil change an filter. My bike I change way more often but thats from hard use an shared transmision. but I will go 400 miles or so. I have even sent the oil in to have it annalized. Hasent ever came close to failing.

My 2 cent's

I use Yamalube, but is there anything cheaper that I can get but more durable? If so where could I get it? :) Im also pretty new to the whole WR450 thing, I came off a XR250 and I was curious to know how often to change the oil, the manual says every 500 miles. Only problem was that when I searched I saw so many varying numbers, I don't know how often to change. Is every 300 miles to much?

P.S. Sorry I'm kinda off-topic but it least it's still related to oil :ride:

If you pull the dipstick and the oil doesn't look brand new, change it...Usually 100-250 miles.

I also use and love Belray Thumper Oil :)

Agreed, and the dipstick is usually showing the cleanest looking oil at the top.

I go 400 miles absolute max, but usually change somewhere between 300 and 400. And when drained, my oil still looks kinda brown, but not black at that point. If I thought my oil was getting very discolored at 200 miles, I'd change it before then.

Yamaha recommended is every 600 miles or five rides, I think it was.

Lots of threads about oil changing. And lots of strong opinions. Someone mentioned that until he sees test data that shows better engine wear due to more often than the manufacturer's recommended intervals, he doesn't see any point in more frequent changes. I haven't heard of any but maybe some of you guys have? :)

This link is to a study comparing many manufacturers oil. It is long but very interesting for someone who really wants to know how their oil performs. I personally won't use a full synthetic in an engine until it has around 1000 miles on it because synthetics lubricate so well that rings and other mated parts might not seat right. The myth about bearings not spinning and therefore wearing flat due to synthetics being too "slick" has been busted though. In a modern 4-stroke turning 10K+ rpms I would go 500 before changing from the dino oil. I run Amsoil MCV 20W50 exclusively in my Harley that is air cooled and much harder on an oil's temperature boundaries. The study answers your question on one oil rating to another.

I don't run the synthetic in my WR because I feel the limitation of the filter necessitates very frequent oil changes that I can avoid due to the superior filter I get from Amsoil for my other bikes and vehicles. Good luck.

I use 30wSAE pennzoil. The guy at the MickyDs drive through window recomended it, cuz that is what he uses in his 94 Honda Civic. He said pennzoil can withstand the pressure of 89FWHP, and with my bike being under 60FWHP its more then adequate. :ride:

oh and I've always used Bel-ray in my 125 2smoke...and I shall in my 450 :)
