so what is the best to use synthetic or non synthetic in hot wethear and not to cold in winter i want one oil for all the year

 

synthetics are going to cause clutch problems year round, A great year round solution would be to run Quaker State 10w-40 year round all conditions.

DPGRDI :-

what do you mean in Quaker State and can you give me some brands name pls...


so all of you guys say that the synthetics oils are bad on the clutch plates so your advice is to use a non synthetics oils and the best number is 10w-40 20w-50 15w-50 can any one tell me wich one to pick for all the year condition .

 

can any one tell me which one is the best between this product ( Pro-Honda HP4 10W40 , mobil 1 MX4T 10w-40 , or the normal mobil 20w-50 non Synthetic )

 

Cooldevil, save yourself the headache and go buy you the Honda Hp4 in the 10W40 and you will be able to run year round with it. I come from Wyoming where it is extremely cold and the oil works fantastic and I have ran in 115 deg F and it ran flawless there too. I have no problems with the quad overheating nor with the clutch slipping, even under the added stress on NOS.

 

Ok ok ok. Oil talk.
Here you go...

The Mobil 1 MX4T is a full synthetic. It has friction modifiers for your wet clutch. No problems there.
Mobile also makes "mobile 1 V Twin 20-50 4cycle MC oil" It's designed for those engines that require a a 20w-50 weight oil AND use wet clutches. Here in so cal, that would be my choice. I'm still breaking mine in, thus still using dino-oil. I've had great luck with MX4T in my sportbikes. The clutch simply grips better than with regular oil.

Another option would be Motul 20w50 (series 3000). This oil (although a dino-oil) works great with the clutch and gearbox also.

Stay away from "Mobil 1" for cars! You clutch will LEAVE YOU IN A HURRY!

Also, be aware that you need some extreme pressure ingredients in the oil (as your oil is shared with your gearbox).

I hope this answers your question.

PS: I've never used Honda HP, but I understand that it's a good (appropriate) oil, also.

i went to my local dealer to find the 10w-40 oils they said that you will not find this kind of oils in here because they use this kind of oils in the cold weather you only will find the 15w-50 and 20w-50 in here because of the very hot weather .

 

I use the Amsoil 4-stroke synthetic oil it's 0w-40. I have never had a problem with it. B4 that I used Bombardier's synthetic, that worked great too, but was $9.95 a quart.....almost $50 for every oil change[img]i/expressions/face-icon-small-disgusted.gif[/img]

On the bottle it says........It is recommended to replace all 0W-40, 5W-30, 10W-30, and 10W-40 motor oils. Also says, for use in : Yamaha, Suzuki, Honda, Mercury, Kawasaki, Polaris, AND BOMBARDIER motors and transmissons.

One question though, it says it does not contain friction modifiers and is recommended for use with clutch plates in ATV's and motorcycle transmissons. What does that mean?

 

Actually its the other way around. Friction modifiers WILL make your clutch slip. thats why the label says that it does not contain them.
Friction modifiers are used in posi-traction drive axles in front wheel drive cars to allow the clutches to slip better when turning corners. Without it, the front tires churp, grab and skid.

Certain friction modifiers are also used in expensive specialty oils like Mobile-1 and many oil addatives to reduce friction in the moving parts of your engine.

 

this topic could go for ever. ask 10 differn't guys 20 diff answers. never had any clutch problems w/mobil 1 synthetic (running a stage III kit all types of racing) but find out for you'r self. i like the fact that at temps low in the winter i can run the same stuff as when 90 out during summer with excellant protection, i've had my clutch apart after a year with mobil 1 with no signs of any heat at all. some synthetics are very much purpose built, there combination of aditives and blends are more specific to some applications like the wet clutch motorcycle oil from mobil. so take it for what it's worth, after to long you'll be so confused you won't know what to use!!
