Mobile 1 4T 10W-40 question

I recently bought an 03 GSXR 1000 from a local dealer. Having been out of the sport for 10 years I have some questions. I asked the dealer about running full synthetic oil in the bike. They told me that was a NO NO due to the Kevlar clutch in the bike. He informed me to run conventional car motor oil in the 10w 40 weight. I really love synthetics and love Mobil One oil and want to run this in my bike. Mobil One has the 4T 10W 40 motorcycle oil that states it will work with all bikes. Is what the dealer said true or can I cahnge the oil and run the Mobile 4T synthetic oil with no problems?

i just put that exact oil in my 07 600 and you would not believe the difference in how smooth the shifting and i love it i didnt ask the dealer but have always ran synthetic in all my bikes always and never had a problem imo go with it!

just to make sure i wasnt telling you wrong info i looked in the manual and mobil 1 racing 4t meets and exceeds all specs required by suzuki for engine oil hope that helps

I use nothing but Mobil1 4T Racing Oil in all my bikes, never had a single issue with clutch problems.

Your dealer is FOS.

Your dealer is FOS. +1

Your dealer is FOS. +100 to that. I run that same oil and haven't had any issues with my bike. Car oil is fine as long as it doesn't have friction modifiers. That stuff will cause your clutch to slip.

so if youre going to run full synthetic but yet youre not gonna switch to a motorcycle oil speciffically designed for wet clutches? thats dumb. i know a couple AMA mechanics and thats a huge problem that they see all the time. people think oh its the best car oil so it must be good for my bike. wrong. motorcycle oil is different than car oil. think about it. does your car have a clutch inside it? nope sure doesnt. so a lil advice, if you want the best lubrication and life. go to a motorcycle oil like amsoil or motorex. its worth it.

I wasn't planning on running car motor oil in the bike. I was talking about the syn. motorcycle oil's. My intentions were to run the 4T oil from the start, but the dealer kinda knocked me off track. Thanks for the help!!

Thanks for the help!! Find a different dealer to get advice from, the one you are talking to is an Frickin IDIOT!!!

Your dealer is FOS. yeah hes a hot shitty mess, i have used this oil in my 2001 1000, and my 2006 1000. No problems.

I bought my bike used with 7,000 miles on it and since I bought it all I've used is the Mobil 1 4T 10-40. It's got a little over 30,000 on it right now with no problems at all. Last time I had the valves adjusted the mechanic told me it looked like it was brand new when he took the valve cover off :D

I just changed my oil on my 07 1000. I used the mobile 1 racing 4T also. It seemed like a good oil. I noticed it ran smoother. It does meet all the requirements from the suzuki manual and it's for motorcycles wet clucth.

I use it...no problems thus far.

I went ahead with the Mobil 1 and like always I was pleased. The engine is alot smoother and even more quiet than before.

The main difference between car/motorcycle oil is anti-sheer additives. A cars oil doesn't have to lubricate a transmission or a clutch like a motorcycle oil which is why you are not protecting all of your motor with car oil. :headshake I just purchased the Mobil 1 4T Racing oil for my bike and like what I am hearing about it and can't wait to try it out. :yumyum: L8R, Sterling

That's my ONLY bike oil. Shifting is like cutting butter!

I've put a couple thousand miles on my bike after changing to mobile 1 4t and I am very pleased. This will be my oil for years to come.

Actually the difference is that automotive oils contain friction reducing additives, which can cause slippage in wet clutches. Other than that, they protect the engine and transmission perfectly fine.

Been using mx4t for years now, great oil. Nothing like the first time switching from conventional to syn though, the bike seems to come alive and shifts like butter. That is, if butter could shift:headscrat:D

I've just changed to this myself, on my k8 600. First thing I noticed was way smoother transmission. I likey.

How do Mobil 1 Motorcycle Oils Differ from Mobil 1? Fully synthetic Mobil 1 motorcycle oils are specifically engineered for use in motorcycles. The formulations are based on the proven technology used in other Mobil 1 automotive products, yet they are optimized for the unique requirements of a motorcycle engine and/or transmission. Mobil 1 MX4T is designed for sport bikes. Most of these bikes have multi-cylinder/multi-valve engines and use a common sump, which means the engine oil lubricates the engine, transmission and wet clutch. So unlike Mobil 1 for cars, Mobil 1 MX4T has no friction modifiers, which could lead to clutch slippage. The motorcycle oil also has more phosphorus/zinc for enhanced wear protection at high engine speeds and high loads. In addition, Mobil 1 MX4T uses different dispersant/detergent technology for better high-temperature performance and engine cleanliness. Mobil 1 MX4T is also offered in a different viscosity grade than Mobil 1 for passenger cars. Mobil 1 V-Twin oil is designed for air-cooled, large-displacement bikes. Because of their design, these engines can generate very high localized oil temperatures and high overall bulk-oil temperatures. As you know, a typical air-cooled V-twin's rear cylinder gets a lot hotter than the front cylinder � it's a matter of airflow. When it's hot out and you're stuck in traffic, the oil temperature in your bike climbs rapidly. Above about 250�F, conventional motor oil is going to break down. Mobil 1 V-Twin synthetic oil is good to above 300F. Like Mobil 1 MX4T, Mobil 1 V-Twin has high levels of phosphorus/zinc and the same high-temperature detergent technology for superior wear protection and engine cleanliness, even at elevated oil temperatures. And it's formulated to protect against wet clutch slippage. You can use Mobil 1 Motorcycle oils with confidence, knowing they will protect your bike in extreme situations where conventional motor oils simply can not stand up, including extended high-speed operation and prolonged idling in summertime traffic.

Thanks for the info

geez … MOBIL Corp should give all you guys a free sponsorship or something. Never used it here but I'ma go get some now!

I run mobil one in my suv and car. Would like to run in the bike. I am sure it makes for some smooth shifting. Where does everyone buy this at? My local dealer was 12 something a quart!!:fu:

It's not cheap. I paid $10.95 a quart at Cycle Gear.

Wal-mart was $8.48.... They were out so went to Advance Auto Parts and they Price matched..... JMG

8.48 at wally world? I need to look next time i am there. I would be willing to pay that.

I paid $8.99 a quart at my local Kragen Auto Parts here in NorCal.

Mobile 1 racing oil from Wal-Mart for me as well. :bowdown:

have any of u tried shell rotella 5w40 synthetic, good stuff for the $$$ and its safe for wet clutches, im useing it and u can get it at walmart for 16.00 in the blue jug
