Pro Circuit runs 0-20 in their 250F's, but I don't know how long they would last in a regular bike.

And have not had a single problem with my bike. My brother had an 00 426 then an 03 450F and didn't even change oil this frequently. I think you people who change the oil every other ride or so are wasteing $$$.

I'm with you to a degree. I think every other ride is a bit extreme unless you're doing hardcore racing... then again, some guys ride every ride like a race.
OTOH, I think the factory recommendation (600 miles for Yammy!) is a bit extreme in the other direction.
Personally, I wouldn't stress going 200 miles IF I were running synthetic.

This is coming from someone who goes 7,500 between changes on their vehicle... 100k and it doesn't burn a drop, but it has been fed M1 5w30 and M1 filters from 2,000 miles.

When it comes to high performance dirt bikes, some of us subscribe to "better safe than sorry". It costs me $40 to change the oil in my truck with synthetic, so I'll take a high quality lubricant and "chance" going to the factory max interval. It costs me $20 to change the oil and filter on my dirtbike. I can afford to change it once a month.

You guys are WAY too anal about the oil thing. Been riding my 01 426 every weekend (about two tank fulls a weekend) for the past 4 years. Use the cheap(not the R) Yamalube. Change the oil MAYBE every three months(12 rides/24 tank fulls of gas). And have not had a single problem with my bike. My brother had an 00 426 then an 03 450F and didn't even change oil this frequently. I think you people who change the oil every other ride or so are wasteing $$$.

It's true, the 426 is a tough bird. But as a professional car/motorcycle mechanic for 35 years, I've seen a lot of engines that were treated like that. They "never had a problem" either, but when they were opened up for some routine work, or when they finally did need something major, we often found that nearly everything was worn to or just past the servicable limit. Not broke, not ground to bits (well, sometimes), just worn out. The owners were extremely disappointed with the cost of restoring their engine. I'll spend $400 a year to avoid that.

OTOH, I think the factory recommendation (600 miles for Yammy!) is a bit extreme in the other direction.

Not really. If you average 45 mph, which is pretty high, if you really think about it, that's about 13.3 hours. I usually shoot for 10 ( I use ride days, rather than hours, and factor in intensity and conditions, but it comes out to about that). If I'm changing oil more often than I need to, I'm OK with it.

Average 45? Yikes... I peak at 45-50 on pavement getting to/from the trail :)
I'm really comfortable at 35 on fire roads, and probably average closer to 15-20.

Then 600 miles would be 30 hours. You see my point? :)
I used 45 to avoid having the 18 year-old MXers complain that they go much faster than (*). :)

Ya, but then my buddy reads this and sends me emails saying "See! I keep telling you that you're too slow!" :p

This is the exact same thing I tell all these people. Glad to see we agree on this. :)

They still have red cap. Your just looking on the wrong site.

I don't think the Mobile 1 red cap 15w-50 is discontinued, I just bought 2 gallons of it at Wal-mart and it was in the newer looking container like the gold cap. Red cap was next to the gold cap on the shelf, in gallons as well as in the quart bottle. :)

Nonononononononono.... :)

The "new" redcap is NOT synthetic!

Now... for you SoCal guys who have plans to ride Ocotillo (as soon as it dries out), the Pep Boys in the north end of El Centro (maybe the only one) has a BUTTLOAD of redcap left on the shelf as of 2/17/05

I emailed Mobil 1 and they say that red cap is discontinued and that the oil I bought was stock that they are clearing out.

I run Castro 10-40 regular oil in my yz 450 2005 & have no problems. Why does everyone want those high dollar oils.

Read your owners manual. Keep in mind that the oil has to be rated for a wet clutch application. Not all labels specify that. Not sure if the letter ratings indicate that like?

Mobil 1 MX4T (10w-40) or "V-Twin" (20w-50) are still around. Made from the same M1 base stocks specifically for motorcycles with wet clutches. Also, M1 Truck and SUV is a fleet graded oil that may be usable.


I second the MX4T. It is made for this application. Red cap 15-50 and other auto oils have additives that can cause clutch slippage and don't provide as much protection as the MX4T.
