Using Regular Car oil

I Drag race my bike aleast 2 weekends a month along with riding to work and everywhere else so I change my oil more fequently like every month and a half @ $12 a gallon for motorcycle specific oil that can be a bit much so i started using one of the high milage car oils with some friction modifier added in for those that don't know what friction modifier it's liquid added to limited slip differentials in a car to help the clutches grab better. question is will this hurt the rest of the motor? done it 3 times now bike runs fine can make repeated passes with out the clutch chattering or getting grabby. I know motorcycle oil is specific to motorcycles because of the clutch not the metals in the bike but will the friction modifier hurt the lubrication of the engine and transmission???

I'm don't know if a friction modifier would hurt the rest of the engine or not. But, you can run automotive oils as long as they are the correct grade and minimum recommended API service, and that don't have friction-reducing additives present, such as Rotella.

I read somewhere to use bike specific oil only.

The Suzuki manual actually specifies SF or SG oil, which is an automotive grade. Any plain SF or SG oil that is not "energy conserving" can be used in a motorcycle with a wet clutch, with acceptable results. That isn't to say you aren't better off using a higher grade, motorcycle specific oil (e.g. JASO MA). Personally, I use a motorcycle specific premium synthetic oil myself, and that's what I would recommend.

use motorcycle oil. i used car oil on my old 2000 ZX-6R and as soon as i put it in i had problems with the clutch. It would not disengage fully and it caused the bike to jump forward on startup and inch forward at intersections. just use whats meant for it. even if its not fully synthetic. oil is always cheaper than engines/transmissions. or whole bikes and body parts if somethin really goes wrong

I use royal purple 10w40 car oil with no problems.

Can I ask a dumb question, why not just use motorcycle oil? costs? I'm sure like previously said oil cheaper than bike work,or engine/ trans work.

$12 a gallon for motorcycle specific oil... I use semi synthetic motorcycle oil and wish I could get it for $12 a gallon. :hmmm: For me an oil change cost around $30 for the oil and filter...

don't cut corners with your bike use oils that are for a bike if you cut cornners and start being cheap it will cost you in the long run

LOL Hey man I'm gonna change the oil in my car this weekend. Maybe u could come get it when I drain it out for your bike. u'd save alot of money. LOL Maybe use the saved money for future bike repairs....LOL.

Why does my k7 gsxr say change oil 600 miles then every 4000 miles. 4000 seems like an awful long time to wait for an oil change. I run 93 gas in bike, and cheap gas in my car...so why would I go a 1000 more miles on my bike with out an oil change?? anyone know why this is?just curious.

Does the owners manual for a K7 call for 93 gas?? I mean if they are wrong about the best type of gas to use then they are probably wrong about how often to change the oil as well.

Well the sticker says like above 91 which means 93. I won't run anything but 93 in the gsxr. Question wasn't about gas. It was why is the service manuel calling for 4000 miles, instead of 3000 miles.

Your the one that brought up gas not me. I dont know why they recommend 4000 miles but I feel fairly certain that they know what they are talking about. Will changing every 3000 be better, maybe slightly, but then again, so will changing every 1000. If they recommend 4000 thats probably good enough for me, then again if they recommend 87 octane gas, thats good enough for me as well.

(not for argument purposes), What kind of bike do u have? Does it say 87 gas? just curious. Ha ha, you caught me on that one! My GSXR 750 is a 99 model and I dont actually have an owners manual, I do have a service manual and it does say that Suzuki recommends 87 octane gas. Newer models may require premium but that I do not know but I am just assuming that it would be regular gas. There are several threads on there that deal with octane and its obvious that people believe different things. But I still say that if your owners manual says 87, that they have tested it for maximum performance and thats what they recommend. If yours says 91 then I would use as close to 91 as I could get. Again there are several threads on Oil and I have gone through most of them as well. Changing your oil more often is not hurting your engine but at the same time your engine has been tested by Suzuki and I dont think they would recommend 4000 miles if they really believed 3000 was significantly better. If you feel you run it damn hard or gotten it hot, thats kind of up to you, they dont know every condition that could possibly occur to your bike. I use synthetic oil in my vehicle and I go 10,000 miles between oil changes. I put 175,000 on my Toyota 4x4 and never had an internal engine malfunction and never used significant amounts of oil between changes. I have over 100,000 on my Chevy doing the same thing....would changing every 3,000 be better....probably, but not significantly better in my opinion.

Car oil is fine! Get on psychobike and see how many people use car oil, a ton. Especially those that change it very frequently. As long as it does not have the energy conserving label, you will be good. When I use to run my turbo bike, I used castrol 10-40 without any problems. The more often you change the oil, the better.

The SG and SF oils of years ago would work great in motorcycles at that time, but show me where you can still get an SF or SG specific oil? Some motorcycle oils will put that on their oil bottles to show that it complies with the older recommendations, but automotive oils can't. Moly is now finding it's way in most oils and when it is designed properly for it's intended application it works great. Honda for years in their manual warned not to use an oil with moly in it, but now their oils are loaded with it. Also many bikers have used diesels oils with no problems, but now one has to be cautious as in 2007 they changed their formulations using many new type additives so the jury is still out if it will or will not hurt wet clutches. Actually there is some postings on the www.600rr.net site concerning diesel oils. There is two reports of clutch problems using the new diesel oils, but that doesn't mean anything yet as they may have had worn clutches getting ready to go. george ADG

It states to use 87 minimum. Minimum and optimum are 2 COMPLETELY different things.

Key words.... "use to" Regardless of Brand, I always recommend a MotorCycle Specific oil with a JASO Rating of MA, better yet, MA 2, but never MB. There is definitely a difference today between M/C and Automotive oils. Bob s.

The answer to all my oil needs including bikes, cars and even lawn mowers. Works great on everything! http://i204.photobucket.com/albums/bb16/oldstuff333/rotellat.jpg

^^^^ Ditto, that Rotella T is the truth:thumbup:

Is there Oil Analysis or ASTM Testing to support that ? Bob S.

Thank you, I use Castrol 10w-40 every 3000 miles.

I use royal purple 10w40 car oil with no problems. +1, I too use this and runs just great!

Thank you, I use Castrol 10w-40 every 3000 miles. I use AMSOIL MCV 20W-50 and the AMSOIL EAOM Filter every 10,000 miles or more, verified by Oil Analysis. Bob Schultz

i am doing my first oil change on my 87 gsxr 750..bought a quart of lucas(she's got 21k on her) and the rest is mobile clean 5000...as far as i can tell, there are no anti friction additives in it...should work, right?

o and one more thing, since this is somewhat lube related.. on an old gsxr like mine,is a little gear noise normal on accelerating?...it shifts fine and all, and doesnt make an intrusive noise or anything, and the chain and sprockets are in good shape and tensioned pretty well; but theres a mild sound of gears meshing ,mostly when i accelerate..is it the way the gears are cut or what? it does it in every gear too.im just gettin used to the bike and have only put like 58 miles on it since i purchased it.thanks all

Probably not, but it is your bike. We are hearing more and more reports of clutch chatter when Mobil 1 automotive oils have been used, and then you are going to add a friction modifier to it ? My suggestion is to buy the Proper oil. If you are hung up on Mobil 1, buy the MX 4T 10W-40 and DO NOT use an additive.. If you think you need an additive, you just need a better oil. All those additives are crap. There IS a difference between automotive and MotorCycle Specific oils. If anyone tells you different, they have no idea what they are talking about ! o and one more thing, since this is somewhat lube related.. on an old gsxr like mine,is a little gear noise normal on accelerating?...it shifts fine and all, and doesnt make an intrusive noise or anything, and the chain and sprockets are in good shape and tensioned pretty well; but theres a mild sound of gears meshing ,mostly when i accelerate..is it the way the gears are cut or what? it does it in every gear too.im just gettin used to the bike and have only put like 58 miles on it since i purchased it.thanks all Change the oil with a MotorCycle Specific oil, make sure the chain is lubed with a proper chain lube, not WD-40 or the like..

i got an 07 busa and i use pennzoil full synthetic in it an runs great . As far as octane mine gets more hp from 87 than 93 . i also can feel the difference in pick up and torque on willies !:D:arsenal
