Motor oil weight

[ThoreauHD]

Hi,

I am currently using Mobil 1 0W40 weight oil.

I am looking at Amsoil, Redline, and Lubromoly motor oils. Which weight of these should I pick, and which brand holds the best on these 15 year old engines. Just from your experience. Or should I stick with Mobil 1 and fogetta 'bout it. Thanks.

id stick with mobil 1 if its working. its the cheapest out of all the brands you mentioned and you can get it at wal mart.
