There is a lot of confusion about oil in motorcycles. Specially marketed "motorcycle oil" is a lot more expensive than oil sold for cars, but is it really safe to run car oil? Yes, just make sure it meets SG, SH, SJ, or SL service requirements. Generally, you are better off with a heavy-duty oil for motorcycles, such as 15w40, below is a list of oils known to work well in motorcycles:
  1. Chevron Delo 400 15w40
  2. Mobil Delvac 1300 Super 15w40
  3. Pennzoil Long-Life 15w40
  4. Quaker State 4X4 Synthetic Blend 15w40
  5. Shell Rotella-T 15w40 (my personal favorite)
  6. SuperTech 2000 (WalMart) 15w40
  7. Valvoline All Fleet 15w40
  8. Castrol Syntec Blend Truck and 4X4 15w40
a Really good choice HAS always been Mobil One 15w50, but recently they changed their formula from TriSynthetic to SuperSyn, which has additional friction modifiers, which may make it no longer a good choice for bikes. This is still up in the air, with people having mixed results, but I say, why risk it, try one of the other ones above!

Now, this may seem sketchy to you, and you're thinking, yea it may work, but will my bike die in a year? In the June 1996 Issue of Sport Rider Magazine, there was a report called, "100,000 mile Honda CBR900RR." The owner used regular Castrol GTX car oil, 20W50 in the summer, 10W40 in the winter, changed his oil every 4000 miles, only changed the oil filter EVERY OTHER time. When this bike had 100,000 miles on it, they dyno'd it up against an identical bike with only 6,722 miles on it, and the horsepower and torque curves were virtually identical! The magazine later did a follow up, with the same CBR at 200,000 miles and going strong, so as you can see, the oil had no affect on his bike.

So, you may wonder, "Why then, is motorcycle sooo much more money, if its the same stuff?"

Well, because they sell motorcycle oil in smaller quantities, more packaging, smaller orders, less sales, more cost per quart. Just recently, some of the major oil companies have caught on to this, and have started selling their own motorcycle oils in auto parts stores and even places like Wal Mart, and they are MUCH closer to the price of regular car oil, because once again, they are the massive companies, they move a lot more oil, and have less cost per quart. So, when you buy the really expensive motorcycle oil for your bike, what you are paying for, is not better oil, you're just paying for that companies costs. Get it? Good. Save your money for better things, like new parts!

Thought I would bring one of the O.G. posts back.


I lifted this exert directly from the Mobil 1 website:

So how is Mobil 1 for passenger cars different from Mobil 1 for motorcycles?

First, let's be clear about Mobil 1's overall benefits compared to those of conventional motor oils, whether for passenger cars or motorcycles:
Superior long-term engine protection.
Superior high-temperature stability.
Excellent low-temperature starting.
Outstanding engine performance.
Low volatility/low oil consumption
It's a little hard to generalize about the difference between Mobil 1 passenger-car motor oils and Mobil 1 motorcycle oils. That's because not all viscosities of Mobil 1 passenger-car oils have the same levels of zinc and phosphorus, and there are even greater differences among the three Mobil 1 motorcycle oils. In general, Mobil 1 motorcycle oils have:
Additive packages balanced differently for motorcycle engine and transmission operation. For passenger vehicles, fuel economy and emission system protection are higher priorities. These require low phosphorus systems and the use of friction modifiers. Motorcycle oils do not require friction modifiers for fuel economy and for better clutch friction less/no friction modifier is optimum. Motorcycle oils allow the use of higher levels of antiwear additives such as ZDDP (phosphorous).

I'm not saying you cant use Mobil Delvac or such oils, but even they arent "cheap", over here car oils vs motorcycle oils have roughly 10euro difference in price, in some cases car oils are even more expensive. I'm personally taking the "better safe than sorry" approach to things, because atleast I can go and complain if something happens in my bike due to oil and they arent going to be able to answer "sir, well the oil you used isnt a motorcycle oil, so we cant compensate you for anything". Also what if the oil companies had increased friction modifiers without any notification and you mess up your clutch with it? Motorbike clutches dont take an awful lot of beating regardless if its a wet clutch.

Just my opinions on things, take it with a grain of salt. But seems a bit foolish to buy a 20000 dollar bike and then taking a gamble with oils. Its kinda like buying a SLR mercedes and taking it to jiffy-lube to be serviced. :p

My bike is a '94, pretty sure my warranty ran out a few years ago.

The oil companies aren't going to compensate you for anything anyway.

Even if their oil causes your $20,000 motorcycle to blow up. They'll stall and stall and stall until its been 47yrs getting to court to pay out all the while the $3.85 payout is being spent by your lawyer.

If it blows up best bet is to take it back to the manufacturer under warranty.

i used to think there was no difference....i used to blow 900rr engines every other month, literally, since i switched to amsoil i haven't blown any motors up, car oil is not designed for a motorcycle wet clutch either
