Havoline SAE30 Engine Oil - Safe to use?
Saw some (50+ qts) Havoline SAE30 engine oil on clearence shelf in Wal-Mart. They are $0.30 each, that'* right, $0.30. I couldn't help but grab a few to stock up. At least I can use them for the lawn mower. But my question is: can I run this in my 10W-30 spec'ed vehicle? I live in Houston, TX, so it'* pretty hot down here, especially in the summer time. Any comments/experience welcomed. Thanks.
If you like to know the Wal-Mart location, PM me.
