I changed my oil the other day and was just thinking.. since I lifted the front side, will there be any oil residue oil left in the tank when I drain it?

 

I think most people lift the front only to drain the oil... it's the trans and diff that need to be level when you refill the fluids.

Should be fine, a little dirty oil won't kill anyone, you're talking about probably less than 1/8 of a quart of dirty oil and then adding 5 fresh quarts...

 

You'll never get ALL the oil out no matter what you do.
