Transmission Oil Choices, What To Pick

[steelehead]

     

so after reading all this i am really confused, i have to get some oil for my son's ktm 50 sr adventure. i've been using 2 stroke oil not sure what type, when you squeeze it, it filled the reservoir.....any info or chart

i checked my owners manual, and it states .25 1 gear oil, shell advance EP80, now to find it.

just go to any auto parts counter and ask for EP80. the brand really wont matter, though for about 40 years that I know of the Euros have suggested shell a lot. never could find the same products they suggested on this side of the pond.

All right, It is time for me to change the oil in my cr500 again and a thought came to me. I have an unlimited supply of mobil delvac 1300 15w40 diesel engine oil. I have been riding in warmer weather, 85-95 degrees. It does not have any markings for friction modifiers or anything else. Can I use this in my bike? I could change it every ride if need be, It is literally free for me. If it is not a good choice I will continue to use mobil one. How about in a ttr-125? Thanks

There are SO many different views on oil, but recently I have been using shell rotella with the same thought that you have with the delvac oil. I would say give it a shot, and if you don't get clutch slip then your good.

When we had a Honda shop we used the 55 gal bulk oil on transmissions on the bikes, never had an issue with it either. Makes for a lot of oil changes for a lot less money, in my opinion because I change my oil very frequently I can get away with a more economical grade of oil, with 5 dirt bikes and a street bike I could spend a fortune on oil very quickly, and I am using rotella in all the dirt bikes and the street bike.

Thanks

Is there any harm in trying? It cant hurt anything can it? I dont think I would run it in the winter but I think I will give it a try. Thanks.

been running atf in my bike for 6 months now.. i use a magnetic drain plug as well to catch any metal debris but there is never any when i go to drain the fluid. i sometimes go 10 tanks of gas before changing it and the fluid is still red.. and my clutch plates and gears look perfect... im going to stay with my atf. it also makes the clutch grab a lot harder

As Scott mentioned Shell Rotela T 15-40 is also a diesel oil. It's all I run in all my bikes. If Delvac is similar I would think you would be ok. Check this link http://motorcycleinfo.calsci.com/Consumables.html

I actually ran the delvac for a while in my RMZ because it was what I had at home (I was running it in my PSD).

I've since switched to Rotella and I think I prefer the Rotella for dirt bikes -- It just seems to shift better.

However both oils worked well.

I used for my kx 250 non-detrgent 30 weight oil for the gearbox

Okay here is my question. 3 years ago I put regular red super tech ATF in my 1998 honda cr250 2 stroke...I loved it because it was cheap AND came in the huge jug size. I'm very maintenance savvy. I like to take care of my bike and do maintenance often. I sold the bike 3 years went by and 2 owners later I bought the bike back. I ran up to the dealer and have to have gear/tranny oil so I grabbed their 80w synthetic stuff. Pretty expensive for just a quart and that only fills it up once...And it was formulated for motorcycles...So I'm trying to figure out what I should use here. I like saving $ and changing often on ATF but is the synthetic still better?

In the end I want to do what is BEST for my tranny/gears so which should I choose? Thanks alot. Really appreciate the knowledge given here. This is a great thread. Again the bike in question is my 98 honda cr250
