Hellooo all,
Quick introduction as this is my first post (although I've marked where my question starts if you want to skip ), about a year ago me and my partner started looking for a narrow boat to call our own after enjoying many holidays previously on the canals. Fast forward a year of intense research and lots of boat viewing, to a couple of weeks ago and we can now call ourselves proud owners of our first narrowboat
There’s number of issues to sort out, it’s defiantly a project boat that’s going to take some time, but by the end we will have put our own stamp on it
A lot of our research has been done on this forum, and I’ve never posted before because as is often said, search the forum and it’s bound to have come up before. However I’ve run into an issue I could really do with a definitive answer for (if possible, many opinions might be about to follow )
Question
I’m servicing our engine (I’ve always serviced my own cars so this isn’t too out of my depth). We’ve got a Lister ST3 air cooled, with a LH150 gearbox and reduction box.
The oil needs changing, especially in the gearboxes as it’s emulsified.
So to the point now, what oil do I need, as far as I can tell...
Engine: 20w50 API SF/CC and 7.5 litres of it (preferably mineral not semi-synthetic)
Gearboxes: (both the main and reduction box) EP 80w90 GL4 and 1.2 litres in each box.
My worry is, should i be strict with the SF/CC, some people seem to suggest don’t stray from that grade at all?
Same with the gear oil, can you use GL5 on these boxes, or must it be GL4? As far as I can tell GL5 would be okay if certain parts aren’t brass, however I don’t know if they are or not.
Also do those amounts sound right? I aware too much oil can be as bad as too little.
You’re help will be greatly appreciated, and chances are I’ll be around on here asking a lot more questions, and hopefully in time being able to give my knowledge back to someone else in my position now
Cheers,
J
