Oil & Gas Ques. on 95 Explorer - Ford Forums

GJSmackdown · 07-27-2006, 14:56

I have a 1995 Ford Explorer XLT, 4x4, Control Trac. It has 156,000 miles on it and thus far no major problems or repairs. I bought it with 86,000 miles on it and have used only Mobil 1 Drive Clean 10w30(now called Mobil 1 5000) and Bosch Oil Filters. My question is with the mileage it now has on it should I switch over to 10w40 permanently or just for the winter time, or should I just stick with 10w30 all together. I've used nothing but the 10w30 since I bought it. Any suggestions or comments will be greatly appreciated.

For my gas question. I've heard it's a good idea to run a higher octane in the winter time, such as 89. I usually run 87 all year and maybe once a month if that run 89. Any difference in running 89 or higher in the winter time vs 87?

Thanks.

The gas you run will not really make much differance. The PCM controls that.

As far as the oil goes, I suggest 10W40 on an older engine with high miles. It will not hurt it at all. Actually, I run 15W40 in both of my older vehicles year round.
