The tire shop put 5w20 in my 03 ST. YIKES! So when I got back to work I noticed on the receipt 5w20. I called asked to speak to the manager. I specificly asked for Full Synthetic Amsoil 5w30. I even explained in the cap has 5w30 in bright yellow leters. After much ado, he appoligized and offered to put 5w30 in for half the cost. I said no thanks but I was having valve stem trouble, which I will post shortly with those results. Needless to say they didn't charge me for the valve stem repair on all 4 tires.
So I went to the auto parts store and bought 5w30 Royal Purple. I just finished changing the oil only. Not the filter. My question is that ok or should I change the filter too? I read some where that 5w20 don't like the SOHC V6 engine in Rangers/Explorers/Sport Tracs. I won't mind changing it but I only put 20 miles on the filter.
