No 10w40 oil still looked pretty after the end of one enduro. Castrol 10w40 looked better than the rest. In Josh's bike, even that oil had seriously lost lubricity before the race was over. The oil in mine was very black. One race. The WalMart 10w40 oil did no better than the Texico 10w40. In my bike, it seriously lost lubricity by the end of the short course. With Castrol 20w50, my oil would be just starting to turn dark (these were new bikes during the test) by the end of the enduro. In Josh's bike, the oil was starting to break down just a bit. (note: Josh's (air cooled) DR350R would get so hot that he blistered his foot through his boots in three different races. He would run that bike WFO the whole event.) The summary is that at that time ('96 & '97), Castrol and Valvoline 20w50 was the only locally available oil which would protect our engines for a whole race.

It's good stuff. non-synthetic? I thought Mobil 1 IS synthetic. -- Charles '99 YZ250

I can get a gallon at Walmart (ugh--that's the ONLY thing I've ever bought there, simply because no one else nearby carries it) for about $13.00 making it pretty reasonably priced. The real reason I've been using it was because our resident oilman Jim Cook recommended it's long lasting lubricity based on his calibrated finger test. Clutching/shifting has never been better. Before that I primarily used Bel-Ray Gear Saver 80w trans oil, generally more expensive than Rotella. We've burned a clutch or two on that. I'm not convinced that Rotella T has changed its formulation. The specs. on Shell's website seem the same. <http://www.shell.com/home/Framework?siteId=rotella-en&FC2=/rotella-en/ html/iwgen/leftnavs/zzz_lhn2_4_0.html&FC3=/rotella-en/html/iwgen/produc ts/product_rotellasynth.html> I do know that there are at least 4 different products that all carry the Rotella T name, but only one of them is the 5w40 full synthetic. This product doesn't have any of the incriminating "Energy Conserving" labels associated with wet-clutch bad juju. Jim, if you're listening, are you still using this stuff? -- Charles '99 YZ250

Hope I'm not confusing the issue by inquiring on oils for 2 different bike types (currently 4 bikes in the collection - 2 2stroke, 2 4bangers) But yeah I did inquire on the 2 stroke tranny oil for the 250cc bike since to this day I'm not sure what to use except that I'm not crazy about the idea of spending $12/litre on 'gear saver' label, even if it in fact is as good as the price denotes. Charles are you sure you paid $13 for a whole gallon and not just a litre (quart for you USians)? That seems awfully cheap for full synthetic oil. But if you used it and find it worked better than say, the Castrol 10-40 or even the cheaper Wallymart 10-40 for the 2 stroke bike, then I may just try it. It's due for a change immediately. As for the 4 stroke bikes I think I'll just stick with the cheapo 10-40 for both the DRZ and the GPz, since I don't ride these hard and they are mostly city commuters. As for my owners manual recommendation (for the DRZ400) incredibly it says to replace the oil every 60 hours. Do they realize how far one goes on 60 hours? I estimate I'd ride the bike for at least 3,600km based on this: it takes me 12 minutes or less to commute the 12 km to the wife's work, across town, at speeds between 65 to 90 km/h and of course, several damned red lights. 3,600 km seems like quite a stretch. I thought that 2,500 km between changes to be plenty but others claim to change every 1,000km. That's just 622 miles. Sure seems like overkill. And with 4 bikes to baby I definitely want to minimize the hassle of changing oil unnecessarily.

Yep, that's a per gallon price. I like it better than the gear saver dino juice in my 2 strokes. -- Charles '99 YZ250 |
