What kind of oil do you use ?

[wahlrite]

I have a 400 EX stock, the sticker on the frame says 20W50, I was wondering if anyone is using any other oil than the 8 dollar a Qt. "special" oil honda sells? synthetic iswhat im really interested in

I also know that any oil with a friction modifier is bad for the wet clutch.

also this quad is opperated in 110 deg F ( arizona )

Thanks

Castrol syntec. full synthetic 10w40 is what my 450 gets. its good stuff.

Amsoil synthetic 4 stroke.....10-40 in the spring and 20-50 when it gets hot. Does the trick. :devil:

I use spectro Pro SX full synthetic 15-50 in the motor, and Honda synthetic in the tranny.

I can highly recommend Rotella T (full synthetic) 5W40 in the 400ex's. You can get it at WalMart in a dark blue jug. One gallon is around $17.

Valvoline ATV 10W-40 4-Stoke Motor Oil.
It's made specifically for 4-Stoke Quads and it's Wet Clutch Friendly. It's $2.49 a quart at AutoZone.

http://www.valvoline.com/pages/products/product_detail.asp?product=77

Here's what the their website has to say about it:

Extreme Condition Performance - Thermally stable formula maintains proper lubrication to protect engines under extreme conditions.
Wet Clutch Protection - Optimal frictional characteristics for high torque, smooth shifting and proper protection of the wet clutch.
Corrosion Resistance - Advanced additives help protect against water, deposits and other corrosive materials to keep engines clean.
Maximum Horsepower - Proper additive balance for maximum horsepower.
Minimal Wear - Increased anti-wear agents minimize wear from metal-to-metal contact.
Shear Stability - Shear stable viscosity improvers better resist oil film breakdown.

Amsoil 10-40

[QC400EX03]

Was using Honda 5w30 for winter but now i try Amsoil 0W40_ !

[Warlord]

I was tired of getting ripped by amsoil so now I use any synthetic oil designed for diesels or heavy equipment. Mostly I use esso xd-3 0w-40 but sometimes I'll use rotella 5w-40. Much much cheaper than "motorcycle" oils and they have very high additive levels.

[redline400ex]

I honestly can't speak for any other oils, but I can say I use Amsoil in everything I own, and I've never blown up an engine...lol Kind of surprising because I don't drive easy, But I do take car of my things...
Amsoil 10/40 for 7 years on my 400ex, doesn't smoke, and motor works stronger than any other 400ex in my area... So there's your proof... If you drive easy and do your regular oil changes and maintanance I'm sure as long as you use an oil that is for your bike you will be fine, but if your someone that revs your bike and likes to wheelie everychance you get then I would suggest Amsoil... ;-)

[mr._bowtie]

Surprised nobody else uses it... I run Kendal 10-40 in mine. The stuff is awesome, we also use it in our drag car. The stuff holds up really well from change to change, its slicker then alot of stuff I tried. Plus it dosent cost nearly as much as bigger names like Amsoil or Valvoline... I really cant say enough good about it.

These guys keep giving me **** about me using Car oils in the Damn Rex .

NOW , my Mechanic wants to tell me that Car oils are lacking in some areas a certain level of chemical , cant remember what metal it was , and this is the result of my bike smoking , i.e , Rings going .

I believe this to be nonsense . Are some of the oils listed above used in Motor vehicles , and can anyone tell me what the major differences , if any , there are between car and motorcycle oils ???

[Def-e-nition]

???

[OnTheEdge]

Automobile oils supposedly aren't made for wet clutch applications. They've worked fine in our quads though so whatever works.

[Jramion]

Resq's replyat the beginning of this thread gave a link to Mobil1's web site that explained the difference in motorcycle oils. It was fairly informative. So maybe the mechanic was correct in stating that car oil was making the quad motor smoke. I don't know for sure. All I know is that the next day I get off I am going to be chaning the oil for the first time in my 400ex and I plan on using motorcycle oil, as recommended.

[flamed360]

I run that Repsol semi synthetic from honda, and i must say she runs really well. I thought they were just rippin me off for 6 bux a quart but it really makes a difference.

[Iliketogofast]

Motorcycle oils are designed for a wet clutch, and nothing less than a motorcycle oil should be used in a motorcycle. I've never had a four stroke engine blow on me, but I did have a clutch go out one time. ;) Never used car oil again.

[ohsobad_chevy]

yeah, car oils most general contain friction modifiers and other additives not suitable for a wet clutch. Again, Amsoil has done very well for me. :cool:

[Def-e-nition]

Thats it . Im switching to amsoil , Or whatever Bike oil I can find .
I chose to be wise , I'll never know If this cost me a set of Rings , or whether it was simply in the line of competition ,. but Im not prepared to go through another wiseco set again .

I'm switching to Bike oil . If it uses enough Oil to make me want to start buying Car Oil in bulk , Then I'll simply re-do the engine over , sooner .

I had a little oil problem the other day. Went trail riding this past Sunday and had to walk my bike across some deep water without it running. Well water got in my crankcase so now i have water in the oil and it's just sitting in my garage cause i haven't had time to go get oil for it. So a friend of mine told me to drain the bad oil and put just regular 10-w30 oil in it cause it's cheap and let it sit there with that in it until i get the good expensive oil in it. Does that sound right to anybody just as long as i don't start it with 10w30 still in it?
:ermm:

[Def-e-nition]

Do It .
Get that water out of your crankcase soonest bud .Water in Anywhere where it shouldnt be is not good .
I also used the cheap oil .

Now I'm having to do an 05' Motor over because it has begun to smoke .

[TXATVRIDER]

So it's cool to just put some cheap 10W30 oil in it for about 2 days until i get some good expensive oil in it?

[TXATVRIDER]

P.S. How long can it sit in the motor and not do any long term damage? It's only been 2 days and there's not that much water in it?

[Def-e-nition]

Water speeds up Oxidation .
Ever see a rust stain from a tin can on cement ?
If the Engine runs , heat is good , but if It's standing , give the bike a few blips on the starter to throw some oil around.
depends how much water got in .

[TXATVRIDER]

Not alot, just enough to tell there's a little bit in the oil. You have to put a drop on your finger and rub it a little to actually tell there is some water in it. Thanks
