5W30 Oil for Ford 500
Just traded my '95 Taurus with 235,000 mi. for an '05 Ford 500. Owner's manual only calls for 5W20 oil. No temperature charts like they used to have.
I got a couple cases of 5W30 Valvoline. Any reason I can't use it? Which oil would actually be better for the engine? I think the only reason they went to such thin oil was to reduce resistance and improve fuel economy (government standards .... squeeze every fraction of an mpg). But, it seems like pretty thin oil to me.
You can't argue with 235,000 mi. with 5W30 and the engine was still not burning any oil. Not synthetic oil either. Standard Valvoline.
