Diesel oil for a scooter?
« on: September 06, 2009, 06:24:18 PM »
 :o
My shop manual for my Grand Vista says to use 15W-40 oil. What little of that weight I can find in this area is for diesel engines though some say it can be used in gas engines too.
The question is why is such a heavy oil needed in a high-revving scooter motor?

...yup..that's all I could find also...the diesel, which I used for a while, in my Agility 50..

..in the case of the A50, I attributed it to the fact thats it's air-cooled, and runs kinda hot..

..I change it about every 500 miles..

..further investigation uncovered a spec of 10W-40..

..I found that on a sticker that's on the bottom of my flip-up backrest/passenger seat..duh...

Hmmm...nothing under the seat.
Guess I'm stuck with the 15W-40.
I have to admit it makes it easier as I have a diesel pickup truck.

So the diesel fuel will also be completely acceptable with my People 150, right?

Probably a typo, but oil, not fuel! ;)

..I ran the 15W-40 diesel OIL in my Agility 50 for about 6 months, because it was all I could find in that weight...

..also, on the oil bottle, it states that the oil is safe for gasoline engines as well as diesel..

..I experienced no problems, but I can't say that it's compatible with everything..I just don't know...

Yeah, I did mean to say OIL and not fuel.  My apologies.

I went with the 15w-40 diesel oil today on my oil change.  So far, so good.

The MAIN difference between diesel engine oil (ROTELLA), and gasoline eng oil is the cleaning agents added to gasoline eng oil. If your make says it is safe for gas engines then it has been blended for MODERN diesels that cannot run on standard diesel fuel (high sulpher). Hope this helps. Have you tried finding Castrol Syntec? It's the best eng. oil in my opinion.

..I've been debating with myself whether or not I should switch to a synthetic...I ride daily, 800-1000 miles a month..it seems that this past summer, my oil has been breaking down rather quickly...It's been pretty hot around here too though...Guess it'll be a little better this coming winter..

..What do you find to be a benefit in using the synthetic?

Without sounding like a comercial... Synth. is designed to take the heat, It has a higher shear strength, and it will NOT leave organic deposits (sludge). I use NAPA full synth. gear oil, and change about 3000 miles (no leaks here) I also use golden spectro 2 cycle (for the past 30 years) w/ no bearing failure, ever..., and in my '87 pathfinder have been using castrol syntec for 375,436.58 miles. I recently replaced the valve cover gaskets, and the valve train looks new. I DO believe in science over dead dinosours!

I have looked for synthetic in 15W-40 but so far no luck.

The 2008 kymco agility 50 says to use SAE 15w-40 in the manual, but the only oil I could find at autozone was Diesel oil for passenger cars and light trucks with diesel engines, but it said SAE 15w-40.  I also saw synthetic high quality racing 10w-40 engine oil for 4 stroke motorcycles, but I did not buy this.

I correctly changed the oil in my scooter and cleaned the filter using the 15w-40 diesel oil and my scooter sounds, maybe smells, dont know if im imagining it, and doesnt run as well as it did before. There is a large decrease in acceleration and lower top speed, I plan on bringing it into the shop monday, but could i have used the synthetic 10w-40 oil?

Also wordslinger, in your signature, what is the $100 50+mph mod you have on your scooter.
