I have used 10w40 in everything for years. cars trucks mowers everything.  I tried to go with straight 30 for the mowers but when I had to top off it seems all I could find was 10w40.... I would buy a few quarts of 30 when oil change time came and didnt ever seem to have any left over for  "top off" needed between. having one weight oil for all is easier for me

though I have no OHC or timing belt engines. all my road vehicles are pushrod with cam in block. I do buy "just enough" when I do an oil change on someone else's car  like my Mom's or M-I-L.s since I don't live with either and therefore am not often asked to check fluids in between changes.

So . I decided to go with 10w-30.  Easy to get at most stores. On sale some times in certain stores, Don't have to wonder which oil to put in and when. And I always check the oil before each use.   Noel

I use 5w-30 all year round.  The first number, the 5 in this case, only counts when the oil is cold. Once it warms up, it's 30 weight. Synthetics are even better, since their viscosity remains stable in both cold and heat, but my 420 doesn't seem to like them much...it doesn't use any oil with 5w30, but does with synthetic.  I am thinking of switching to a semi-synthetic next time I buy a case though.  I'll have to talk to the guys at Oil Mart and see what they recommend for that.
