When I went to Advance, the guy there told me there was a discount if you get Motorcraft oil with the Motorcraft filter. The only weight they had was 5W-20 Synthetic Blend. I asked him if that would be appropriate for my engine and he said that it's what is used for all Ford applications now. Is this true? Is it fine to run 5W-20? I'm pretty sure my 89 2.9 calls for either 10W-30 or 5W-30. Should I use the Motorcraft oil or should I use the jug of Valvoline I have in the garage?
