GL1500 oil???

As long as the oil is not energy conserving (Slippery stuff in it that the clutch may not like) any oil will do.

I used automotive oil in mine for quite a while but found it more and more difficult to find an oil that didn't have "friction modifiers" in it. Worked that one out when my shifting started to do funny things and I went back and read the oil bottle a little closer.

So..........I now use a good 4 stroke motorcycle oil (Castrol - which is easily obtained for a reasonable price at Walmart) and my shifting is back to normal.

Diesel oil is what most use, like Rotella, Delo400, etc... since Diesel oils normally do not have the energy conserving friction modifiers. Still read the label and look at the symbol to make sure though.

I've never ran "Motorcycle Oil" in any bike I've ever owned and so far never had any type of oil related problems.

What bikes have you used Diesel oil in successfully?

I use have used Rotella T synthetic for over 5 years in my GL1100 with great results.

I'm thinking of using Castrol 10w 40 oil in my goldwing. It does not say that it has any friction modifiers and is not energy conserving oil. I just like what it says about high rpm engines, stress, and heat on the bottles. Also I must live near the only Walmart that doesn't sell motorcycle oil so that is how I picked the Castrol out. What do you think?

I use Rotella in both my Honda's. 96 GL1500 (250,000 km )& 84 750 Shadow
(40,000 km). :waving:

amsoil....:readit:

DELO 15-40, can't miss. Nice shifting.

1100, 2 1500's Goldwings for me.
When I rode years ago I used auto oil in the Kaw's and Honda's but back then oils did not have the additives like today that can ruin clutch plates.

I don't use Castrol for anything myself. Back in the late 70's or early 80's the engine blew in my dad's near new truck leaving me stuck on the road in a hotel for over a week while I had a shop rebuilding the engine.
Reason it blew?
Castrol oil had sludged up everything inside like caked on grease and the sludge clogged the oil pickup screen!
That truck was bought brand new and always had the oil changed often.
Just plain bad oil back then I guess!
Probably better stuff now, but I still won't use it!

As for the heat, stress, rpm's I think Diesel oil would handle it better. A big semi truck engine of course is much harder on oil in many ways than a little car engine LOL

I know A Lot of people on this site have good luck with diesel oil however it is not made for the environment that you are using it for. A diesel engine is a different breed of engine. It is a slow turning engine usually below 3,000 rpm's. Also the byproducts of the diesel are quite different from a gas engine. So yes it does work and works well but IMO the oil was never designed to run properly in a gas engine. I'm sure a lot of you will disagree with what I just said, however this is my opinion based on some reading I have done over the years.

oh yeah oil....opcorn:

If you look on the bottle of a good auto oil , it has a diesel rating on it also. Just saying.
Try the Delo from Walmart and your Wing will like it. Made a believer out of me with my 88 GL1500 and might save my tranny for a while longer than ANY of the other oils i tried. Your 99 should have the stronger Valk tranny in it, but still might shift smoother.

I've been using Mobil 1 15-50 in all my bikes for the past 20 years. Doesn't have friction modifiers. Works great. $25 for a 5 quart jug at Wally World.

Not all diesel oils should be used in automotive or motor cycle applications. They are different in the additives that are used. Also did you know that rotella oil is 20% recycled oil? After many hours of reading about oil this is what I have learned. Whatever you like the best is the best oil you can use. It's all about how often you change it and also how often you change the oil filter.

Oil and filter every 3000 KM.

Speaking of filters.............I only use Fram!

Thanks for the response by actual users of diesel oil. In the past when I have used diesel oil in petrol/gas applications it has been fine unless the engine is worn, then the cleaning effects of the diesel oil can lead to excessive oil consumption once the carbon has been cleaned out from the piston rings.
