    I would like to know what oil brand and oil weight people are using in their mowers and trucks. What has worked the best for you in the past or even presently? Do you use the same weight year round, or do you switch to a lighter weight oil during the colder months? Thanks!

    Pennzoil 10w30 in everything except the wife's new car. I buy it 24 at a time and one oil makes things a little easier.

    Castrol GTX 10w-30 in everything, except new truck GTX 5w-30, and older 4cycles straight 30.

    Im looking to use a synthetic in the new truck so I don't have to change it so often, like that clean 5000 stuff from mobile.

    Thank you for the responses thus far. Please keep them coming! I still have not seen a response that stated whether or not anyone switches oil weights during the Winter?

    delo 400 15w-40 in everything. a diesel oil should keep the air cooled engines real clean, and be able to handle the soot that comes from the higher running temps that the air cooled engines run at. the delo has given me the smoothest running I can get so far. even better than mobil 1, which is an exellent oil. btw, I also like that delo has a good amount of molyibdinum disulfide. go to www.bobistheoilguy.com and read "moly basics".
