I would and have used car Mobil One in motorcycles,I would rather and know it would be better than a diesel oil.

No it want make your clutch slip.

He want gasp the basics of our conversation.
but the viscosity of the situation slips his mind.

 
See, Bill has taken the trouble to clarify that perhaps he really doesn't know what the Mobil he's is talking about.

Bill, 'ol "it isn't motorcycle oil" himself is saying a non JASO car based group III oil should be used in a Savage engine, especially an SN formulation with less than 600 ppm of ZDDP with moly added back in to it to try to take up some of the rapid wear slack.

No wonder he thinks we should all have rapid cam chain and flat tappet wear -- and slippy clutches too !!!

   

Now Bill, WHEN did you use this good Mobil 1 oil?    

When counts in this question, as Mobil 1 before SM actually had some ZDDP in it and it didn't have moly in it either.   Red cap Mobil 1 Extended SL formulation actually spec'd out to be good oil, but that was what, 5-6 years ago now.

 
The only S40s that are showing wear are the ones using Rotella oil in them, (some proof please) Theres people on here that have driven 50000 miles on s40 with no problem, (who please) My wifes GN 400 went 26000 mile nothing done to it and no problems (and this applies how?).You guys are your own worst problem playing around with diesel oil and see how much its costing you, you have all kinds of problems.   (Now this is true, both Verslagen and I have modded and ridden the pure tee stuffin's out of our Savages -- our problems from this don't stem from the oil we use per se)

10w 30 mobil not the extended I use that in my car.I use Klotz 15 50 in the S40 and when I change my 1500 it will be klotz 10 40.I'm saying Mobil One is better than that diesel oil you guys have all the trouble with.


OF replies:   Bill, not only are you not using a JASO motorcycle oil you are using the wrong summer weight of car oil in it.   10w30 is too light for the 1500 Intruder in summer time use, Suzuki recommends 10w40 for the 1500 Intruder for year round use and simply doesn't tell you you can use 10w30 in the summer at all.  

Now, I realize it gets cold up around the Great Lakes so I could see using a good 10w30 JASO bike oil when the snow is flying (winter only) but you freely admit to leaving the 10w30 car oil in your Intruder for two solid years, summer and winter.

Why do you go so durn thin on your bigger displacement (750cc per bore) motorcycle when you "overweight" the Savage with a 20w50 Klotz synthetic?

 
Don't worry about it Greg, when an oil war is due, an oil war is due  

But a good follow-up question might be: Is it ok to let your engine run hot as long as the oil is a good synthetic that can handle it without breaking down?  Probably not, huh.   Adding an oil cooler is still a good idea.


OF replies:    Nobody plans to overheat their bike due to idling in traffic.   It happens though.   Having a sump full of T6 means it is a total non-event to you instead of a potentially "bad thing happening to ya".    

Remember, all "over the road" big diesel engines have oil lubricated turbochargers and turbo hot side bearings get VERY HOT in use (500+ degrees is not uncommon) -- Rotella T6 lives in this environment unharmed for hundreds of thousands of miles.


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


And at the very low idling Savage oil pressure levels and flow levels, just how much oil movement and cooling effects do you thing you are gonna get out of that little oil cooler?  Yeah, the one that is sitting still with no air flow going through it right now either,  just a sitting there right next to that hot arsed jug?  

And the tiny amount of oil in the head oil passages and the head cam oil bath is just a sitting there, smoking & slowly turning black ....    Seems the shiny expensive oil cooler tries to cool the oil down in the sump, but it doesn't affect the oil up in the head right now at all ......



What is plumb funny to me though is the people who are paying more dollars for three $8.99 quarts of a name brand dino based "motorcycle oil" that simply can't cut the 500^o+ overheating mustard than they would pay for an entire GALLON of T6 at Walmart's every day low $22 price.  

Remember == T6 is noted as being very very heat stable (it is not even going to notice your overheating episode at all).

   

Wow, I've been missing the party !
