Oil Question

I am getting ready to change oil on my Toro riding mower.  It has a Kohler engine in it and calls for 10W30 oil.  I have a 5  quart jug of Penzoil 10w30 oil in the shop.  What is the difference if any between the Penzoil oil I bought at the auto parts store and the universal oil 10W30 that is recommended for Kohler motors that comes with the tune up kit that I was researching on-line.  There is a price difference probably because the universal oil comes in quart sizes where I am buying the Penzoil in the 5 quart size.  I have quite a few small engines that could use either 30W or 10W30 oil and it would be great to buy it in the larger size to save money.  What are some of the best options that are being used for small engines that come in bulk sizes?  Thanks,  Sully

    I am probably going to start an oil war as everyone has their favorite brand but it really doesn't matter as long as the API classification is the same. It will be marked on the container.

    Thanks Roy, I think the API class is the same for the Penzoil oil vs the special universal Kohler oil.  I bought the Toro riding mower used and I am not sure what the previous owner used so I am going to go through it and get everything up to current on the maintenance.  Do you have any recommendations for 30W oil for small engines?  Sully

    I prefer to use 30W in small engines during the summer season, I believe it offers better protection. We have to remember these engines operate under brutal conditions, hours of wide open throttle under load in hot, dusty conditions. They need all the help they can get. One exception I am aware of, there may be others, are the Kohler Command engines with hydraulic lifters, they do better on cold start up with multi weight oil.

    I always use pennsoil in all my equipment.
