My Bike has about 900 miles on it and im getting ready to change the oil in it for the first time. I've read the owners manual and Suzuki is pretty specific as to what kind of oil should be put in this thing. 10W-30 and the oil should not be energy conserving. I went to the local grocery store and picked up some Valvoline Synthetic 10W-30 and come to find out it was energy conserving. Im going to return it after work today and was wondering which oil everyone here uses?

Thanks for the help!

Of course you need Motorcycle specific oil. And 10W30 is thin, I would go with 10W40 at least if you have you region has temps over 70 degrees F. And W50 if you live in very hot states.

So I cant use regular motor oil? It has to be motorcycle specific? Will anything bad happen if I choose to get an oil thats not recommended by Suzuki such as 10W40?

I live in Michigan and it can get pretty hot here, but majority of the riding season it floats around 75-80.

Then I wouldn't go lower then 10W40 half synth and I would only recommend changing to synthetic after the 4000 miles service. And YES you need motorcycle oil specific, because the clutch and gearbox also use the same oil for lubrication. General engine oil would not lubricate as good or wear out faster.

Okay, Thanks Kadett.

Oh yes . The old oil topic. You will get a great many different answers(opinions) . I've used Mobil 1 15-50(non energy conserving) in all my bikes with no problems . Change oil and filter(if it has one)every 4000-5000 with water cooled, every 2000-3000 for air cooled. What ever you go with keep it topped up(if needed), and change regularely. Good luck---Luke

Which brand of Oil do you use? ...... Coconut.

Aaaaaah, cocoanut oil, we may have something here . Let me see, coconut oil, some lime juice, vodka. shake well pour over ice in a tall glass, garnish with a sprig of mint . I'll have to run this by the Hound Crew(Zipper, a well blended pit bull, Wally, small brown and yappy from Mexico(so he claims), and Max, lop eared German shepard),I'll be willing to bet they will approve .

I've found that most auto parts stores and even Walmart carry motorcycle oil. There have been many articles on the subject of motorcycle oil being different because motorcycle engines have more stress, and as said by another poster, many use the same oil for the transmission. Worse gets to worse you can mail order it.

My local grocery store has some Valvoline Motorcycle Oil 10W-40 that I might end up getting. Otherwise I was going to try Maxima - Maxum4 Premium Oil from Motorcyclesuperstore.com

I hope you are not going to get your lettuce from Pep Boys. ( )

You can use car oil if it doesn't have friction modifiers (energy conserving). When in doubt, use Motorcycle specific oil (although it costs more).

Well its more of a Walmart than grocery store, they sell more stuff than actual food and crap.

I was just yankin your chain.

It doesn't matter where you buy your oil, as long as it fits the manufacturers' recomendations.

I use Pro Honda HP4S fully synthetic oil. It only comes in 10W30.

the need to use motorcycle specific oil is BULLSHIT IMHO
you need to use an oil that has no friction modifiers in it - no doubt about it, but motorcycle specific - CRAP

If the oil meets the specifications stated by the OEM and the weight is in the weight range for the temps you ride in and it is NOT energy conserving (or DOES NOT contain friction modifiers) then use the stuff if you want to.

I personally use a diesel engine oil in my bikes at a weight of 20W50. I'm not telling you to use the same oil as me tho. It's your choice.

So long as it meets the specs stated ion your user book, gives you a warm and fuzzy feeling that you are using it, use it.

Oil debates will go on for as long as we have internal combustion engines and I'll read about them for as long as my arse points to the ground. It's almost the same as the "how do I run my bike in" debate.
