yamaha 10w-30 oil

[b.walker5]

Will agree to disagree Steve. Been riding for close to 40 years, never paid a mechanic for anything in that time, and have been using 15/40 for as long as i can remember, at least the last 25 years, with no issues.

I have 5 vehicles, (one of which is a high perfromance V8) and with the exception of the diesel truck, i use the same oil in all the rest. Each to his own I guess, but i cant see any reason to change now.

I was talking with the owner of a local bike shop the othere day and he told me that theses days there is so much crap in motor oil that you really need to buy "motorcycle" oil so you don't run the chance of messing up your clutch. He stocks good old 20-40 with no synths or aditives. With a smile he said, "yeh now we get to pay more for the old oil we used to get"

Here's what I use. 100% mineral. No additives.




It's all right saying "I've always used Castrol GTX" or whatever... the thing is, the Castrol GTX made today is vastly different from that made in the 1970's and 1980's. I looked into this with Castrol. I used to be a fan of GTX. It used to be 100% mineral oil. It now isn't. The bloke at Castrol told me that it's just about unrecognisable and amounts to badge engineering!

I'm well aware of that James, but I have been using the evolving product for so long now with no issues I trust it enough to continue using it.

Well, stick with what one trusts, I always say. Confidence in a product means a lot. I reckon that's why I've always ridden Yamahas and love them. I've had other makes but usually very short term and I've never really felt at ease with them, Same goes for oil.

Anyone use/remember Duckhams Q? It was/is green anbd won't mix with any other oil when topping up, doing changes etc.... that's what they said, anyway. I never used it, for that very reason!

I have to agree with Steve on the oil and even though there have been improvements in the friction fighters and enhancements which prevent the oil from breaking down there is another issue. There are flow dynamics with different weight oils that can cause wear and damage. Many of these bikes have wear on them and therefore the clearances are not as tight as a new engine. If you put a lighter weight oil in an engine with a lot of miles or hard miles this lighter oil may not be able to keep the oil pressure up causing loss of lubrication to areas. I would not recomend anyone putting a lower than recomended viscosicty oil in one of these bikes for any long period of time. I also think it is just as bad running oil till it has been beat to death. I do know that the original recomendation for oil included 10-40 weight oil for colder climates. I could actually see possibly considering thinner oil for colder areas of Canada but that would be an extreme.

As for running the 10-30 oil for a short time if you are not reving it hard driving it long distance in heat and the engine is in good shape I do not see it causing a problem for a short term. As for any dealer recomending 10-30 oil I would not ask them anything else and I certianly would not have my bike worked on there.

I post stuff on here you guys have a wealth of knowledge, I should have checked here first before I bought my oil, and put in the wrong type. It's probably not a bad thing you have to change the oil again, because the motorcycle did sit for a number of years. I'm really flushing out the oil system good. Thanks for all the help and advice guys I really appreciate it.

I'm confused by this statement. As the temp goes up the thicker the oil you would want to run not the thinner... in cold weather the thinner oil cold flows better. Heat will break down an oil, even a high quality oil, to thinner than its stated weight.

Yup, I was thinking half backwards there and said that wrong.

I'd have thought all engine oils have additives

Even Castrol say Classic XL 20W/50 has additives, from their website....
"A conventional multigrade engine oil of good all round performance, formulated with high quality mineral oils plus selected additives, ideally suited to older technology and classic car engines. "

I do like the sound of the Castrol oil though James, I looked into it and may be able to get bulk drums supplied by Castrol, they're our preferred supplier here at work. Its API SE which was originally specified by Yamahahaha.

At the moment I use Morris Ring Free 15W/40 and agree its too thin for older engines.

James, all motor oils have additives. Multi-grades in particular were created with additives....

I've spoken to our Castrol supplier about the Castrol XL 20W/50, he's offering me the same discount my employer gets (global pharmceutical giant I ain't gonna name )

He also admitted that its not made by Castrol but sub-contracted, he did assure me theres no way Castrol would put their name on it if it was not up to standard.

Best oil on the planet as far as im concerned. Castrol, that is.

Yes, you're right of course. I think of additives as the modern ones... you know... with cleaning agents, semi-synth bits etc. I'll revise that rash statement of mine.... "Here's what I use. 100% mineral and few additives"!

got it done

i finally got the time to change out the oil with the right stuff. i didnt ride it at all with the 10w-30 i was scared that i might mess up some thing, and since i was going to change it i wanted it all to settle so that when i drained it there wouldnt be any of the 10w-30 in it at all. thanks again for everyones help.
