Maybe it gets very hot in Australia, just a thought.

Not hot enough to justify such a thick oil. They have an obsession with "thicker is better" over there.

Interesting statement given that you have no idea what he might be running it in.

Whatever it is that actually requires an oil that thick in Australia, would require an oil that thick here, too.

I can think of a couple Ford products off the top of my head that spec a 50-weight

I use PP Synthetic 5W-50 in my BONE STOCK 280Z 4-speed car. The bottom end has never been apart and has 158K miles on it. Good compression accross all 6 cylinders. Summertime (NOW) temps are in the low to mid 90s here in South Florida. I drive the car moderately hard---and without an overdrive---75 MPH cruise is 3500rpm. I like and use the a/c almost ALL the time. Oil pressure is ideal and fuel economy has improved slightly over Mobil 1 15W-50. Years ago Conventional 20w50 weight oil was routinely recommeded as the oil of choice in the early Z Cars. Many Z specialty shops still recommend that weight with ambient temps over 20 degrees F. Remember these cars had SOLID LIFTER valvtrains thru 1978.

Some oldies! No problem with the 50-weight there, you've probably been running that in them for a LONG time I bet

Those would be some MODERN examples, yes. Had it escaped your imagination that perhaps he was going to be running the oil in a much older vehicle?

In the post following yours, that was indeed answered.

The attitude that there is no place for a heavier oil really is appalling. On a site that is so focused on the quality and usage patterns of lubricants, I am genuinely surprised at the seemingly intentional ignorance to manufacturers specifying oil weights outside the 20 and 30-weight spectrum, as well as specifying heavier oils elsewhere in the world.

What makes it so hard to come to grips with this concept?
 
I dont see a problem using a xx-50w where the vehicle is being started at a temperature higher than an oil temp. some vehicles won't see for 10 minutes in the northern US. In cases like this id look at viscosity numbers in the tested 40C area to decide oil purchase, as feezing is going to be ignored for the most part. Getting up to temp as fast as possible is the name of the game for emission and economy purposes, which is why it's all 20-30 specs here.

You can safely putt-putt a 0w-20/30 in oz I'm sure but who just putt-putts around? They get the really nice models down there and flog em'. I sure as heck would.
 
hi all, thanx for all the interest

had the triumph since about 1979, all in bits atm

got the norton as payment instead of money about 5 years ago, it runs very well but needs lotsa cosmetic work

bought the rktlll about 18 months ago, had a VERY loose timing side rod, so loose that i was able to lift out one of the big end bolts by hand i.e. the nut was no longer on it

getting the engine rebuilt by an expert, coz i've never pulled down a three cylinder before

and i'll be running MOTUL LE MANS 20w60 in it
