Just did my oil change today and went with some Redline synthetic and a K&N filter. Nice improvement as far as the smoothness of the shifting is concerned and seems to idle a little smoother as well ( could just be me though ). Was a little hesitant to throw that much change on that stuff but i figure i can go a little longer on the oil changes now and the Redline offers really good protection . We will see .

What does Red Line oil co$t a quart?

Set me back $12.49 a quart but i can go twice as long on the oil change interval so it works out it in the end.

I see nothing wrong with that, I have 5 bikes and use Mobil 1 Racing 4T 10W-40 in all of them at about $10 a quart. Red Line is good stuff, nothing beats synthetic.

Hey GSXfun, how does Mobil 1 4T racing differ from regular Mobil 1? I switched to synthetic last fall, does seem to shift silkier. It always did shift smooth, though.

Mobil 1 Racing 4T 10W-40 is a motorcycle specific oil...so supposedly it is different than regular Mobil1. Here's the link...Mobil 1 Racing 4T 10W-40, most people are on one side of the fence or the other on motorcycle specific oil versus regular oil, and not really wanting to start any arguments on the subject...let's just say that when I hold my '02 Honda CH80 wide open for 20 minutes at a time in 90°+ weather...I don't worry about an engine failure

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).

Hey guys, I am ready for my first (600 mile) service and, I'm going to do it myself. I am wanting to know if it's ok to go ahead and switch to the Mobil 1 synthetic now? Or should I wait longer for the engine to finish breaking in?

Some high performance autos come with it from the factory so.....
Personally I wait till 3000 miles, but that's just me, a farmboys son

It's fine. The day I got mine home I switched to Mobil 1.
