yes, yes, yes, lots of words there, but truth is anyone not using straight 30 will be subject to fiery wrath from the heavens for their ignoble acts, and suffer eternally, engulfed in visions of exploding crankcases and forced to drink used, hot multigrade >:D

a10gf - it's not a question of getting bogged down with 'straight 30' or whatever, it's a question of using the oil the engine was designed to run on. Use a detergent oil in an engine with no oil filter (eg our bikes) and sooner or later (usually sooner) the engine will require a major overhaul - if it hasn't already gone bang. Use a 100:1 two stroke mix in an old seagull outboard and it'll be goodbye engine in a minute or two. They require a 30 or 40 oil at 12:1. Horses for courses and all that.

“Professionals” means salesmen, in this case.

it's a question of using the oil the engine was designed to run on.

In the good old days, when the engine only lasted 20,000 miles.

Why did someone have to mention oil, the word oil should be banned on the forum !

I'm 62 now and have been working on engines either as a full time mechanic or "after hours" since I was about ten, I must have pulled down hundreds of engines in that time. In all those years I have never seen or even heard of an engine fail/blow up/wear out prematurely where the cause can be directly attributed to the oil. I lived and worked in central Australia for many years and have seen a couple of engines that were driven for a couple hundred miles on totally wrong oil (oil from a windmill in one case) just to get the people home.

Now there is no doubt in this case Penrite are going to push their own product, they wouldnt be very good at their jobs if they didnt. However I do use their oils in all my bikes, moderns to old ones.

I own a 1000cc Moto Guzzi that I bought new in 1994, it currently has 111,000 k's on it. I have run it on Penrite HPR 30 from new with changes every 3,000 k's which by modern standards is a short oil change period. Now Guzzi's are renown for lasting a long time but my bike after 111,000 k's doesnt use any oil at all, the oil comes out after 3,000 k's nearly as clean as it is when its put in and I have never had to adjust the tappets. All of which means there must be little to no wear in the engine including cam and tappets, no valve recession. Wether this is due to the oil or the quality of the engine is of course debateable.

So my take on the subject is if you use any brand of oil that is a half decent product you will be ok. All the talk about you must run one brand or a straight grade etc etc is a load of bollocks in my opinion.

So there ..........................................

G'day Brian.
I agree wholeheartedly. A good oil changed regularly is the key. I use Penrite in the BSA's and Castrol Active 4T in the Orientals. Just pulled the rHonda 1100 down (due to pinging damage) the mains, big ends and cam bearings look like new after 150K.
Cheers.

I must admit I probably jump up and down more than I should but oil topics annoy me.

Sometimes you read about someone saying you must run a straight grade or something or another and most times its just rubbish.

Those of us that have been playing with bikes for years just put oil in and go for a ride but i feel sorry for someone who is new to old bikes or any bike for that matter and read some of these threads and end up thinking if they dont put the right oil in their engine will explode into a million pieces the first time they start it.

Ok, ok, calm down fellas!

What about the argument over detergent oils, designed to have a remote filter vs non-detergent oils in engines that use a centrifuge filtering, (sludge trap) system?

I once met a research chemist who ran his airhead BMW on second hand hydraulic oil. He reckoned that hydraulic oil was far superior to any engine oil. His Beemer seemed fine to me.
