    My Briggs calls for sae 30 wt with a sf sg sh sj or higher api rating. All I could find at the parts store is api service sl (Pennsoil or Castrol). Is sl a higher rating than the previous oils I've mentioned? I don't want to void a warranty.

    In other words is SL ok to us?

    My understanding is sl is a higher rating, you should be ok. I use Castrol 30w in all of my equipment (Kawis And B&S) and have never had any problems with it.

    Yeah, the SL is on up the line, newer...

    I still don't know why they still recommend SAE30 though.
    I wouldn't run that this time of year if I were you.

    Pour some in a can and leave it outside all night.
    You'll see what it's like in the morning.

    Break it in on some 10w30 or 15w40 instead.

    SL is fine. SL is the latest oil. I can't believe they are still specifying SF. SF, SG and SH are not even available any more. SH and SL are the only 2 currently available catagories of oil. It sounds like the only thing that has changed on Briggs engines since the 80s is the carbs.

    Thanks for the info. I just always try to go by the engine manufacturers recommendations. Above 40 degrees it recommends sae 30 regular oil or synthetic multi-viscosity oil. I though Kawasaki also recommends 30 wt in some of their engines. I don't think I'll use the synthetic while it's breaking in anyway.
    Thanks for the info.

    You're welcome...

    And I didn't mean to sound 'gruff' there about the SAE 30.

    It's just that I, many others, and many MFG's have abandoned SAE30 decades ago.
    I don't understand why some small engine MFG's hang on to it.

    There is no PROVEN benefit to running SAE30.
    It contains no more base oil or anything else.
    In fact, most of it trails the quality of multi-vis pretty badly.

    Understand that really nobody who "is anybody" recommends using SAE30 in their engines anymore. So there is no external pressure to meet increasing specification demands so they can label their oils "______" certified for use in "______" engines. Not like the multi-vis oils for gas and diesel are.

    Next time you are in a store, pick up any bottle brand name 15w40 to see what I mean.

    Really :confused: Here is Kawasaki's recommendation, make sure to read the note about increased oil consumption when using multi weight oils.

    Yeah it says...

    Some oil consumption MAY be expected when using multi-vis oils.

    Check oil more frequently than recommended interval.

    ********************************************

    In other words they are saying that over a 100 hour period, you can expect some oil consumption with A/C engines. Don't wait 100 hours before you check your oil level.

    ********************************************

    There IS NO BENEFIT FROM USING SAE30!

    This is a dead horse already

    If you think SAE30 is soooo superior... put your facts where your fingers are.
    Any of you...

    In other words PROVE IT!

    Show me a data sheet on your favorite brand of dino SAE30.
    I will show you a spec sheet from that same MFG that shows performance eclipsing the SAE30.
    I haven't looked at any of them in years, but I can still almost guarantee it.

    This is not 1970, and your mower is not your dad's pinto.

    Data sheet's I don't have but I have torn down plenty of A/C engines that run commercially here in S.FLA using mulit-weight oil. I have seen what running the wrong oil does to a motor. You know what, use what ever oil makes you happy :) the most important thing is to follow your engine manufactures recommendations and service intervals. (they built it why would they know what oil to put in it:confused: )

    hello , using a low spec oil is generally 4 running in a new engine where u do not want all the additives 4 engine protection [detergents etc] . Particularly where the rings r concerned .Bedding in is top priority . Around 100 hrs running in is a good average figure although upto 300 hrs is not uncommon .

    As every body has stated multi vis may lead to consumption although probaly only slight .
    All later letters superseed the one prior eg SM now is the better version of SL etc.
    Use appropiate viscosity 4 your temp although the average would be 10/30 ,10/40, 15/40 or some even use 5/30 ,5/40 ,5/50.
