Briggs and Stratton 4 hp motor

[huck farley]

I would like some advice from the members regarding engine oil. I change the oil in my bike every 6.oooks. My bike takes 3.2 liters. So that leaves me with .8 of a litre left for top ups. But my bike never uses any oil between changes. So I have 2.4 liters left from 3 oil changes. The oil I use in in the bike is a 10-40 fully synthetic.

What I would like to know is. Would the left overs from an oil change be suitable to use in my Briggs & Stratton 4hp motor mower engine when it requires an oil change, which I do twice a year. The book says to use B&S SAE30 oil. Would a fully synthetic oil fuck the B&S engine. Or would the engine benefit from using clean fresh 10-40 fully synthetic oil. A little feedback please.
Cheers HF

This is just a test, right?

To see if any of us has picked up that after your bikes next 3.2 litre oil change you will have ANOTHER .8 of a litre to chuck in with the 2.4 litres spare you already have...ta-dah! --3.2 litres of oil waiting for the NEXT oil change...!!!!

Shhh!! Don't use logic. This is KB, that sort of blasphemy is not tolerated here!

I asked a simple question and expected some advice from perhaps a motor technician, Your message is real DUMB and makes no sense. I don't need a dork such as you honing in on my posts with stupid remarks. Never was a person more aptly named as yourself. You are indeed a SCUMDOG.

Well I tried running our real mower on Semi synthetic a couple years ago. It didn't go any better and smoked a bit (Used oil). Possibly a bit thin for the old engine?

A scumdog I may be - but a logical one!! - even if not a 'tecnision'!
(still searching for the 'stupid remark' bit)

So why did you post all the clap-trap about the left-over oil then ya wally?

Why does it matter how you happened to have the oil - all you needed to post was "Is 10-40 fully synthetic oil compatable with a Briggs&Stratton motor-mower engine?"

Simply eh? eh?

Some questions...

1) Why do you change your oil every 6 k's?
2) What is a motor tecnision?
3) Does your Briggs & Straton owners manual say "We recommend used oil for extending the life of your engine. If you don't have any used oil, use anything you can lay your hands on or for best results, run it dry."?
4) Exactly, what is the meaning of life?

You'll probably find that the briggs and stratton engine, being a fine example of american engineering needs a 30w oil just to fill the huge gaps in the bottom end. You may even find a banana skin to be beneficial.

It's a lawn mower motor that makes 4hp. It's a piece of agricultural machinery, not a high performance, precision motor. The piston to bore clearance is likely large enough that you'll be burning as much oil as petrol. Stick with the 30w.

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.

1 - Cos guys cant keep me wet.
2 - Someone who knows how to pleasure a woman.
3 - Peanut oil.
4 - Get laid, ride hard, and who cares.

C'mon dude - I went all radical and put 20-50 into my iron-head Sporty instead of the recommended straight 50 weight.

Hell, it started better, idles smoother when cold and never missed a beat so ya can't call ME an 'oil Nazi'
