Motor Oil

what's the best stuff to run?

[DEAL]

just run some Honda brand 10w 40

[RoostinOna400ex]

NOOOOOOOO Dont buy that over price honda stuff just get some mobil 1 sythentic and it depends on your climate for what weight of oil to get!

[mysticfalcon]

how is honda oil overpriced its cheeper than mobil 1 by $1/quart

[nakomis0]

Any decent motorcycle oil should be fine. I would run a thicker oil. The 400 gets pretty hot.
I was using the mobil V-twin 20-50 synthetic 5 bucks a quart. But now im trying the Valvaline 20-50 motorcycle oil, 2 bucks a quart. I change my oil about every 4 rides.
20-50 maybe to thick for stock?, but my 440 gets extremely hot.

every four rides? **** man i know we all like to take care of our 6,000 dollar toys but isnt that a little excessive? im a little new but i cant imagine that that oil looks any different when you take it out than when you put it in! do ride hard as a sum***** or what? i would think that at every 4 rides youre riding 7 to 8 hours a wack?

[twisted threads]

I use Mobil 1 syntetic 15- 50 works great for me.:cool:

Do any of you guys using the mobil 1 have problems with the clutch slipping or is that just hype.

Also does the oil stay cleaner longer?

[400exdad]

No problems with slipping clutches here. My valvetrain is quiet now too! Mobil 1 15w50 Automotive oil! Check some threads. There was a LARGE discussion on it a couple of months back.

[RR900_Pilot]

The key with Mobile 1 is that you want to run the Mobile 1 motorcyle oil.

The deal with the clutch is that the 400EX as well as most other 4 stroke motorcycle engines use the same oil to lube the engine and the tranny.

Mobile 1 automotive oil contains molybdenum disulfide (moly) to penetrate metal surfaces. The concern with that is that when you run this oil in a motorcycle engine with a wet clutch, the moly penetrates the friction plates and causes the clutch to slip.

I had a '99 CBR600F4 and a '99 CBR900RR and I read in a Honda tech sheet that is sent to all of their shops' mechanics that speciffically said not to run an oil that contains moly.

Mobile 1 has recently (in the last couple of years) developed their synthetic motorcycle oil that does not contain moly and is safe for wet clutches.

Hope this helps a bit.

Heh, :square . I do ride pretty hard. My bike gets incredibly hot. The oil always comes out black. Maybe Its more acurate for me to say that I change the oil every 3-4 Weekend rides. If I ride, its ussually on a weekend trip. 1 or 2 weekends burning the heck outta her at Silverlake and shes in desprate need of an oil change :)

I run Mobile 1 15w-50 and love it. No clutch slip at all.. I change my oil after every weekend ride at the dunes... full change including filter.. The oil always looks good but I am just anal and like the bike to have the best posible conditions to work in. I really don't think you can ever change your oil to much.....I am a firm believer that if you take care of the machine it will last you longer.

You took the words out of my mouth!!!!:D :D

[Honda Guy]

So everyone runs Mobil 1 motor synthetic motorcycle oil or regular syntheic oil? I have always ran regular non syntheic (GN) honda oil will it be ok to switch to syntheic?

Is there a better oil filter than stock? How good are the K&N oil filters

[MR.EX-TREME]

YEAH GO AHEAD AND SWITCH JUST DO LIKE I DID BACK WHEN I CHANGED AND RUN IT FOR A WHILE AND THEN CHANGE IT AGAIN AND YOU'LL BE FULL SYNTHEIC AND IV' E RUN REGULAR MOBIL 1 15W-50 SYN. IN ALL MY BIKES FOR YEARS AND NO SLIPPING CLUTCHES EVER!!!!!!!! :devil

[Deathbringer]

Yeah not the Motorcycle oil, just regular old Mobile 1 Synth

[400exdad]

That right, just AUTOMOTIVE Mobil 1. I probably let the Mobil 1 stay in one more ride as compared to regular oil, some folks may go longer with the synethetic. (Me about 4 moderate rides.) I figure, its just 2 quarts, it does get hot and I want my motor to last a long time.

[bpimpdaddy21]

Just out of curiousity, is that 15W-50 mobil one good for the winter? It seems as if it would be a little too heavy to run in the winter, or is it alright? I am wondering because my 400ex has only about 10-15 hours on it, and I am doing my first oil change next weekend, and I am wondering if I should go full synthetic? Is it just better for all around riding?

[jay's 400ex]

i've heard good things bout amsoil! thats what we run in my dads sportsman HO and thats what i'm gonna try once i get my 416 broke in. we run 10w-40 but they got 20w-50 too. its synthetic too in case u were wonderin. peace, later :cool:

[Dave400ex]

[MR.EX-TREME]
