Oil types?

[CookMySock]

Curiously, my bike shop recommended that I not use fully-synth motorcycle oils, as they had some problems with clutch slippage with them.

This was no anecdotal evidence. They tried it - clutch slipped. Stopped trying it - clutch stopped slipping.

Do the math.

edit: seriously, how can it matter a toss? Motorcycle oils are not subject to extended oil-change intervals, so why should we ever need a cutting-edge lubricant?

Because those better quality oils have a better base stock that resist shear longer with having to lubricate the gearbox as well. And they also tend to have higher levels of acid regulators and corrosion inhibitors that are beneficial for bikes that could be sitting for long periods of time between occasional use.

Have a read of this... http://www.calsci.com/motorcycleinfo/Consumables.html

I did, and I quote: "10w-40 oils should not be used in a motorcycle that runs the engine oil through the transmission"
Obvious this Internet expert knows a lot more than many global motorcycle manufacturers who specifically specify 10w40 in literally millions of motorcycles.

Yep - I'd really go by what he says ......

He means mineral 10w40. Synthetic 10w40 is fine. (that was just his summary. He has more pages on oil)

Why? Because that mineral 10w40 oil you put in your bike could soon be only a 10w20 after 1000ks. A good synthetic will hold closer to its viscosity for longer.

Yes they are.

Well Mobil for one. Kelsie Clendon who was the lube technical manager at Mobil when I worked there, used to recommend mixed fleet lubes as being great lubes for bikes.

Actually Dipshit is quite right.

Well this MOBIL employee says that MOBIL engineers wont and Dont endorse such a practice and if you do be it on your own head.

We won't mention the Mini,which was in production for about 40 years,starting in 1959 with oils no one in their right mind would use these days....with engine oil running in the trans.They even had auto versions running in the same engine oil.They were told it couldn't be done.

Well I will stick with what Kelsie used to say thanks. She was the lab manager at the LOBP, she set up the used oil analysis lab then took over the lube tek position in HO.

I use one Valvolene general mixed fleet lube in all my vehicles with the exception of the Roadking that gets a Harley oil Syn 3. I only use one Valvolene oil because its available locally in commercial sized packs at the right price. I can't actually say too much about the Valvolene oil I use, I do change it out very regually and I have never had a lubricant related failure. I have stuck with the Syn 3 in the HD because it's the one oil that HD recommends that can go in the motor, primary drive and gear box, its expensive but it makes it easy for me only having to keep one oil.

Mini boxes were never the strongest box on the planet. The A series gear box be it in a Mini, Morrie 1000, or MG Midget was designed to run on motor oil. The sincro rings in these boxes are bronze and the EP additive in extreme pressure gear oils react with "yellow metals" and turn them into yellow sludge.

Motul 300V for a greener oil.

Think of the children!

Rotella T- API CJ-4 Better for flat tappet cams within OEM specs-NO Cats .13% Zinc
Valvoline All Fleet Good for Gas and Diesel Engines natural or turbo-NO Cats .15% Zinc
Spectro Golden Semi-Syn Good for higher HP applications, natural or turbo, and flat tappet cam-NO Cats .15% Zinc
Kendell GT-1 API SM/SL Good for higher HP applications, natural or turbo, and flat tappet cam-NO Cats .16% Zinc
Valvoline VR-1 Good for higher HP applications, natural or turbo, and flat tappet cam-NO Cats .20% Zinc

I brought some valvoline today. Specs look good.

there is a NZ site for powerup but it is down at the mo...
http://www.powerupnz.co.nz

has anyone heard of Powerup oil additives???

Powerup has no relation to Motorup... Motorup aint that good for cars so not good for bikes, Motorup got taken to court for misleading consumers. Google it...

Powerup is no good for wet clutches.
Boss added it to a Honda Quad, had to drain it after 100k centrifical clutch slipping like mad.

People, two things, read your bike manual and follow the recommendation, and consider the oil companies recommendation, whats so freckin hard about it

[Motu]

Oil specifications change,or are superseded....but your manual and the oil recommendations of the time don't change.In 1987 there were some good 20/50's,now they are a budget oil for worn engines,even oil names that have been around a long time like GTX are not the same GTX of 20 years ago,let alone 30 years.Time to do research for an oil meeting modern specs.

And don't go on about Castrol again Quasi,you are sounding like an oil rep who knows about nothing except pushing their product....I've met dozens of them over the years,none impressed me.

When I went to buy oil for my bike for the first time I took the manual in. I couldn't buy oil of the same specification - they don't make product witch such low specifications anymore.

Bit Harsh Motu dont you think, we are trained on many things sorry your current rep doesnt impress you tho, perhaps its time for a change.
