Bored, what kind of oil do you guys run in your cars/bikes?

I'm running Valvoline motorcycle 10w40 in the bike atm because it was broken in on a conventional and I didn't want to change it, Royal Purple or Mobil1 10w30 in the car.

lol

There's only one kind of motorcycle oil that works at pepboys, so I use that one. I don't have a car, but my moped is also taking 10w-30 for it's break in period. ATF type F after that.

any oil you want to put in it, as long as it isn't energy conserving.  I use 10 w 40 pennzoil in my 4 wheelers, dirtbike, cars, and my gs

As long as you NEVER use synthetic oil you should be ok.

Ewww pennzoil..  I always use Castrol.  I use the weight recommended by the engine manufacturer.  10w40 in the GS.   And 5w30 in the subaru.

yeah i wouldnt use a synthetic oil that holds up better to heat and takes more abuse before it starts to break down.

Has anyone actually lost an engine as a direct result of the make they chose to fill it with??

You get bored and decide to start fights on forums!!! You should go riding when you're bored.

Personally, I use 2% Milk. Skim gives better efficiency, but wears faster. Whole is just retarded. Oh and make sure it doesn't have vitamin D because your transmission won't work.

Rotella T, non synthetic. dino oil I can share with my diesel, and no friction modifiers.

Cheap oil changed often is better than expensive oil changed less often. Not to get to the absurd point of Frankie's claimed 200 mile changes on synthetics (pure waste of money & time IMHO).

Changed at the recommended intervals, cheap dead dino oil that meets the proper specifications is fine. Most of the difference in cost between cheap oil and premium oil is marketing, if it meets the same specs. This motor was designed to work with dino juice. If you look at the dipstick and it looks bad, go ahead and change it early - more often than not, real oil problems come from not checking the dipstick (or not checking it properly.)

10W40 not marked energy conserving (which is bad for wet clutches - you have one of those.) Cheap and generic unless you get enough warm fuzzies from some brand name with advertising BS to make it worthwhile to you to spend more on that. They certainly try to convince you it is - if there really was much difference, there would be a lot less need for spending on advertising, so figure out what all that advertising really means - it's not free, and you pay for it.

I've used the 15W-40 heavy duty oils (aka truck oils, diesel oils) for my last 100k GS500 miles and don't think you can find a better oil for an air cooled motorcycle engine.  Used Rotells T, Delvac, and Delo brands but stick to the Rotella T now that they've tested and added the JASO MA motorcycle spec.

Available everywhere and priced right.

What's so bad about using synthetic oil?

I think the claim is it allows the wet clutch to slip too much.

not if its made for motorcycles with wet clutch setup

  I cant believe this thread has stayed on track as closely as it has so far.    

Synthetic oil is the only way to go, using anything else is just asking for engine problems.
