Just bought 3 quarts of T and a filter from Wally-weird yesterday for Lisa's 800 Intruder. JASO MA rating is right in the front of the bottle. Since she has made the mistake of thinking her bike takes premium fuel (since 1999), I expect to be changing the oil and filter frequently. Heavy duty oils pull a lot of excess carbon out of your engine. They are designed for it, de-coking an engine keeps it running cooler, longer.

Doesn't have to be Rotella. Chevron Delo, Mobil Delvac, whatever flavor Tractor Supply now carries, NAPA (crappa) diesel spec... You want a good heavy duty truck, tractor oil in a primitive engine. Other than the CDI box the Savage engine is a 1930s design. Save all the fancy synthetic this, specialty that for bikes with a high enough powerband to require $10 or more per quart additives.

It's a Briggs rototiller engine on steroids. Even crappy old ND 30 works fine in it.

If you trust the engineers to have gotten it right... they don't ride. They don't care.

Let me synopsize what the Bob boys had to say:

First, it is fairly good car oil for its weight, which is a bastard weight halfway between 15w40 and 20w50.

The SM version of it was a better oil than the current SN version.  

This also points out that Mobil 1 will apparently make abrupt changes in an oil without saying anything to anybody -- buyer beware of Mobil1 in this aspect, you may not get what you just thought you bought.


==============


Now for my question to you --- why do you want to buy a friction modifier type car oil of a weight that isn't specified for your motorcycle's engine and wet clutch?  

Especially from Mobil1 who likes to stick in moly (yep, it's in there at 81 ppm) and other energy star type items in there at whimsy whenever they change the oil on you without telling you?

Just curious ....     (you must like them real "Mobile" slippy clutch plates)

Thanks for the quick reply Oldfeller! I have used it since day one in the 05 Toyota Matrix which now has 113000 miles and is all stock except tires and spark plugs. Amazing car and purrs like a kitten. I have heard grumblings about not using synthetics in a wet clutch because of slipping. But, up until my 87 savage I have always used Mobil1 and never had any slipping in many a bike. That being said, It appears I would be well served to switch to Rotella in the Savage. Any recommendations on weight and type of Rotella?

 
87 Savage, if you like synthetic oil, get Rotella T-6 in the blue jug.   Both Verslagen and I use it and get good results from it.

T-6 is a full synthetic rated at 5w40.   This means it doesn't get thick when it gets cold (oil gets up to the head quickly when you crank up) and it doesn't thin out when it gets hot.

And hot, with T-6 can get very very hot with no issues.  T-6 can get up in the 450-500 degree range before degrading seriously and a Savage engine simply can't figure out a way to get that hot.   Very very hot to a Savage is in the 350-400 degree range.   This isn't going to give T-6 a tickle, much less hurt it any.


=====================


rl153,  instead of popping $17 to buy the booster, why don't you pay $12.99 for a gallon at Walmart and get you some dino Rotella T in the big white jug.   You have been using a dino oil from Suzuki that costs a lot more and you just haven't been getting the ZDDP you need from it.

Read this and understand it is saying the Suzuki branded oil is nothing special at all and it is sub-par to any of the HDEO products like Rotella.

alright ,i'm convinced, wheres the best place to buy the s40 oil filter online? Is rottella T 15-40?

I usually get mine at Bike Bandit.

BTW, is there no other alternative than the Suzuki filter to buy online or at the stealership?

Get your filters online from JC Whitney. Same EMGO filter the dealership uses in their service bays. Trust me, the Honda/Yamaha/Polaris/Suzuki dealer used to buy then by the caseload from the shop I worked at. $4.95 or so versus $10.95 for the oem (priced them today, won't be going back there).

Or send Kimchris a pm and see when she is making a Bent run (she'll know what you mean). Shipping would be a lot cheaper. That shop has hundreds of them in stock.
