Hi all, I'm having trouble finding monograde SAE 40 in or around Melbourne. Are there any good folk on here that are able to help me out with suggestions?
I've used Morris's Golden Film Classic 40 in all my bikes for years. Their website says they have outlets in 80 countries including Oz and NZ. Maybe search their site or email them for your nearest supplier. http://www.morrislubricants.co.uk/
Penrite do strait grades in the Shelsey range for vintage vehicles, however it would have to be ordered in.
The question is why strait 40 , particulalry in Melbourne ?
I run 20w50 in mine with no problems.
thanks Trevor and Jeremy, I'm just following advice (Ron Pier and others in previous posts and Jeremy Atkinson this post.) Others I believe run SAE 50. I have no idea what is currently in my bike but it does wet sump. I'm going to move to a thick/er(?) oil and try not to leave it as long between starts/rides.
I'm in Melbourne also and I've been running 20W-50 for quite some time in my M21 without issues. If it's wet sumping that you are trying to cure it might be better to look into what is causing it.
BSA's have a check valve easily accessed. 16H's do not. If, as is the case with my rebuilt in 1945 norton, you don't want to disturb the grunge of decades; then don't use a modern high detergent multi grade. I suspect that Morris Classic multigrades do not contain such additives, whereas their Vtwin multigrade would. I use that in my japcrap singles and the classic multigrade in my freshly rebuilt M21 as it's cheaper.
Both old sidevalves burn so much oil that I never change it. It changes itself
penrite make it - i went to repco -they ordered it in for me
shelsey medium :
SHELSLEY MEDIUM is suitable for passenger cars, motorcycles, 4WD's, light & heavy duty commercial vehicles (trucks, buses & heavy equipment), tractors and industrial machines that originally specified a SAE 40 monograde grade engine oil fitted with/ without an engine oil filter. Those vehicles that require a higher detergency should use Penrite Classic Medium Engine Oil.
The same question came up on another forum, except the guy was in rural USA. Was given the advice I gave you and he found it on the shelf in his local town tractor dealer.
