Save your good oil for a free oil change every 4-5 fills. B&S motors need a thick, basic oil changed daily. Signed a tecncn.

What makes everyone think 30 is a ''thick'' oil? A multigrade will be a bit more runny at low temps....perhaps you could use 10/30 in winter in Invergargil.These engines have no oil pump,the oil gets flung around with a slinger gear and somehow finds it's way to the bigend.Straight 30 is a pretty good compromise for most conditions.The 10/40 will be great,getting that oil flung around when cold and giving a bit more protection when hot.The quality is irelavent,but remember there is no filter.....

You fucking idiot!!!!! That's the most stupid fucking thing I've ever heard - it'll blow up tomorrow,I promise you.

WHICH idiot - there's a whole raft of 'em on this thread!! (self included)

[Motig]

"Thick" oil ? Do they have IQ tests then ?

Watch your mouth cunt.

The B@S manual advocates the use of multi-grade oils in temperate climates, ours,the oil sold by B@S authorized dealers is a rebadged Fuchs oil,and a total marketing con,

Not much encouragement, So I went and did it anyway. I cut the lawn this morning, The Masport run like a charm, and It also runs much quieter. To those who called me a wally and a fucking Idiot. Sticks and stones. To coin a phrase. I bet you both run Agricultural compressors, and indeed HUCK FARLEY. Thanks to everyone else. Who were less negative than the retards I have mentioned. So you can use a synthetic in your lawnmwer!! They love it.

Well, ya got me there!










So now ya have to but another 4litre oil-pack for the bike eh? huh?

But at least he'll have some left over for the mower ??????????.

It seems I've given Scummy too much bling, lately! So if'n I give you some you can pass it on...


But I really think you and Scumdog are too subtle for this site

[eliot-ness]

But at least he'll have some left over for the mower ??????????.

Ahhh, but by the time he gets around to the next oil change the oil left over in the carton will be just as old as the oil he's draining from the bike. Nobody with any sense would put old oil in their engine.

oh so true, cant use old oil.

now why didn't i think of that?

Well I went and done it, on my spannermans advice. In his words. Any higher rated oil you use, will be much better than the old SAE 30 shit they want to knock of to you for $17 a liter. So my B&S Masport mower has brand new 10/40 Q8 fully synthetic in her. I can report to all the no brainers that gave me a hard time. If you brains were gunpowder you wouldn't even blow your crash helmets of.

The Masport cut my large lawn this morning. No sign of oil burn, and only used half the juice I normally use. Also the loud knock has disappeared from the motor. So we live and learn.

I put USED racing 4T in my mower.It is barely even dirty after being in the bike for 6000 km.15/50 and I change it in the mower every 10 hours.
Still beats the once in a lifetime oil change most mowers get.

[Fatjim]

So that means the 10/40 might be a bit too thick eh? I've heard that stationary engines sometime run way too hot for multigrades and they break down.Basically they just don't need all the stuff that a modern oil has....there is no oil filter so the dirty stuff needs to fall to the bottom and not be suspended for filtering.You can run anything you like,but B&S recommend straight 30.All the oil Nazi's on this site get upset if you use anything but bike oil in your bike - I'm sure they will have stern words to say if you don't use B&S oil in your mower.

Actually, I beleive 10/40 is a little thinner than 30w when cold, and a little thicker when hot.

Remember one oil does not generally provide for less friction than any other, it's just how they perform in different circumstances: ambient heat, sheer forces, contamination, engine performance, that defines them.

A motor mower engine is a little less stressed than a motorcycle engine. It just sits there most of the time at a fairly constant low RPM with the occaision heavy load if your grass is long. It's not a highly tuned beast and therefor will last a long time if looked after (clean filter and oil).
