Engine burning oil

[the picker]

I have a 16 hp Tecumseh engine burning oil. I am using 10/30 oil so I could I use a heavier oil or is there something I could add to the oil?

[ARGOJIM]

Did you do the leak down test yet? I have one that smokes with worn valve stems.

[atc tigers]

How much oil dose it use? Is it smoking real bad?

[the picker]

No I did not do the leak down test has I have no tool to do it.

It is probably burning I/2 litre on 40 km.

I am huge fan of Lucas

Have used it many times in different engines but the most impressive was in my 1965 Starcraft Chieftian 120hp eninge.
Used to burn about a liter every trip out. Put a liter of Lucas in and now do not add any extra oil for an entire season of boating.

The engine only takes 1.13 litres of oil so how much would I have to use.

[Craig_B]

I think its a 1L to 4L of oil ratio.
As long as you keep to the ratio suggested on the bottle it will work out.
Dump the remaining product into your car.

Thanks I will try that.

Back to your oringal question I don't think anything shy of gear lube will fix your problem if it is smoking and what not your motor will probably have less power unless it may be valve guide seal which I do not think is the issue. I think harbor freight will mail you the leak down tool for like 39 dollars . But if you choose not to do it is your choice.

Being from down under (you) I'm not into the litre thing, how many ounces is that about 8? If so you have internal issues, did you try a compression check since you didn't do the leak down test?
Just FYI, you can probably find a new piston and ring set and head gasket, but valves are long gone unless you find someone up there with some on the shelf.

1 liter is about 33 us fluid ounces.. Roughly a quart..

Well dang, must be time for a new engine if it's burning a qt. in 15 or so miles. There are a few threads on here about Tec. swap outs.

Mine was smoking so bad I decided to try to find valves, may have a good used set but since there are 2 sizes of each valve I know I need a disassembly before any further progress.

The engine has about 93 psi of compression.

I now have leak down tool ordered and when I get it I will need help to set up and use thanks
