what oil do you use in your 300ex? the honda manual says I should use 10w40 for my temperature. tell me what you use.

 

I run 20W50 in all my bikes summer and 10W30 winter. I use honda HP-4 and Amsoil series 2000 oil for my quads. I run Bell ray 15W50 in my XR's and I run quakerstate 4x4 in my toyota 4x4 and use chevron Delo 400 15W40 in the cummings.

 

I use HP-4 currently, the next oil change going to 20W50 Honda oil.

 

HP4 10w-40

 

Valvoline 20W-50 during the summer and 10W-30 in the winter.

 

Any of the oils rated for diesels or industrial applications will work well in a 4 cycle quad. And do so economically, Oils such as Rotella T, Chevron Delo, Delvac, Pennzoil Long-Life etc. etc. in the 15-40 weight. All of these oils are SG/CD rated and do not include friction modifiers.

Texaco 20w-50 for the summer, and 10w-30 for the winter.

 

Last change switched to HP-4 20W-50

 

Mobil 1 in my 450es and my wifes 00' kodiak. I've used it in the 450es since new (2 years). No problems.

 

I'm fixing to put in maxima 10w40. I hear its good oil.
