Use old stash of oil in B&S 4 Cycle?

[Mr_Accord]

Hey guys,

I'm going to be pulling out my Craftsman mower this weekend to get it ready for summer. It has the 6.5HP B&S Quantum Series engine. I know this question has probably been asked many times, but I have a jug of Pennzoil HM Dino 10w-30 lying around my garage. Would it be alright to use up this in my mower instead of buying straight SAE30 4 cycle oil?

Thanks

Run 10W30 in my 5.5 Honda all the time.....no worries !

Yes, it's fine. It's even approved by B&S for you.

Briggs and Stratton Oil Recommendations

My father has been using my used 5w20 oil in his older push mowers for a few years now , never an issue. He uses these old mowers to clear the back have of a three acre lot. The mowers he is using now are the old 3.5 briggs and stratton engines. Its simply amazing the abuse these motors will take. The handles break the wheels wear out the carbs go screwy but the motors never stop. My point being keep them full of oil and you will most likely never have an issue no matter what grade of oil you use.

I agree with all...Use the oil no worries.

I've used 2 year old Pennzoil HM 10w-30 in my old Toro mower that had a briggs. I'd still use it today but it was stored in a tent shed that collapsed 2 winters ago.......

Thanks for all the info guys. Glad I can save a few bucks and get rid of some of the oil lying around my garage.

Have a good weekend everybody.

Got a blend of who knows what in my B&S mower that is nearly 3 years old (the oil, not the mower). Because I'm using multi-grade oils of between 5w-20 and 15w-40 it tends to burn a little off, but it runs great.

I think it'd run Crisco on a warm enough day.

Last year I filled my 675 Briggs with 10w-30 and experienced some oil burning, switched to SAE 30, the smoking stopped...

I have a 12 yr old Briggs 2 cyl. Over the years I've run PYB straight 30, Citgo & Mobil 5w30, Maxlife 10w30 and currently it has Trop Artic 10w30. Nothing seems to phase it and it still runs like a champ even with the original spark plugs. It gets an oil change at the end of the season so it doesn't sit with dirty oil in it all winter long.

I ran a garage/small engine shop some years back and I was shocked at how many push mowers would come in for service with hardly any oil in them and what was left was like tar !!
Any oil would have been better than what was left in those . Tuned them up , sharpened the blade and fresh oil and away they went again (for how long was up to the owner) but I always mad a point of explaining that checking the oil level was important and changing at least once a season .

My BIL's love 'collecting' and fixing up old tractors. They run nothing but basic 10W-30 in them, and it works fine.
