Oil Changes

Good Info Thanks, Should i check the oil after it has been warm and then let sit for say 10 minutes to get a true reading. The owners manuel say check it warm but i rather hear from one of you guys here in the fourm.

The other thing you should do is put a tiny bit on your tongue. If it tastes soapy, you're probably ok. If it has a metallic/oily taste, then get it drained because you likely have a pressure issue.

I like to check the oil when I'm buying gas since it's level and the engine is warm. There will be some oil retention in the upper galleries, under the valve covers, ect so warm measurement is the best indicator.

With that said, you really shouldn't have a situation where the oil is retained anywhere in the return areas unless there is excess sludge build-up. The lifter valley, upper cylinder head areas, and internal block low pressure pathways all retain some oil as it drains downward towards the pan, but hot and cold readings should still be within safe levels is you're using the right viscosity for the local climate.
