GC vs Motul 8100 vs Mobil TDT

[Brien]

I have a Suzuki Ltr450 Quad. Im currently using Rotella T 5w-40 in it.
Are any of the oils in the title a better suited lubricant for my quad? It has a shared wet clutch setup.
All three of these oils are within about $1 per qt. Which would you recommend?

Dont you need to use motorcycle oil?
As far as I know, motorcycles, which have a wet clutch, need motorcycle specific oil, because the additives in the car oils make the clutch slip.

It is indeed very important to use an JASO MA specified motorcycle oil. Otherwise you will ruin your clutch.

 

[Brien]

No, Ive researched this topic extensively. Jaso is not required.
Either way, which of those four oils is te best for a small high RPM engine?
Also, if an oil does cause the clutch to slip you can simply drain the oil and refill it with something else

Rotella will work GREAT for you. I use it in our ATVs (Brute Force, Suzuki King uad, Old Honda 300)

It doesnt have moly or at least much of it and won't slip your clutch.

Hi,
Brien - Of the three lubricants you mention, Mobil 1 TDT 5w-40 is the most robust!

I think ill give the TDT a try. I have two quarts of GC that im going to try using. Thatll give be a reference point in addition to the Rotella.
What oil(s) are even more robust then TDT?

 

[Doug Hillary]

Hi,
Brien - In that viscosity the answer is very simple - none!

Awesome. Ill report back with my findings in a couple weeks.
How will TDT hold up to fuel dilution? Sometimes Ill ride for alittle while but not long enough for the oil to get up to full temp. So any fuel from blowby at start up is still there

Hi,
it will be as tolerant as any other lubricant mentioned - probably slightly more so
