US Location and Oil range used??

[cockblocker]

I just wanted to find out what types of oil people use in their 3100/3400 engines.

I live in Mississippi and this oil change used 20w-50 in my 3100.

I used to run 15w-50 back in AR...but then again that was a chevy with cast iron block and heads I am noticing more engine noise now... time for a change Im afraid.

20w-50? Holy crap... I use the recommended 5W-30, and sometimes 10W-30. The car has lived (I guess you can say that) in Oklahoma, South Carolina, Maine, Connecticut, Kansas and Arkansas while I have owned it. Just passed 10 years in April...

5w30

Ouch 20W50 is too thick. No harm will really come of it but I would be using 5W30 (synthetic or normal) like you should be.

I'm in Wisconsin, and use 5w30 synthetic blend in everything, year round.

10w30 Mobile year round, changed in my main commuter (the Euro) last fall, I should change it...I have had so little time. but now I do.

If I lived in the south I would use heavier. Or cali....Beverly Hills...that where I want to beeee... yeah right. :P I had to throw that in.
