Rotella 15/40?? Right choice?
#23
I've ran it with 20w50 that I had left over from the RX7, but I felt that the 15w40 was better suited for the Discovery.

Switching from Castrol 10W30 to Rotella 15W40, we'll see how the engine performs. It's getting hotter here in Vegas so I'm sure it will make a difference. BTW is a Motorcraft FL1A a good filter to use? Wally World stocks them for dirt cheap and had some good results with them in the past.

Just my 2 cents...
I run the Rotella 15/40 from May through Oct. Then switch to Rotella Synthetic 5w40 for the winter. Its worth it and it can be found anywhere for pretty cheap. Even walmart stocks it and its usually 16/17 bucks a gallon here (synthetic is more), sometimes cheaper if there is a sale. Haven't found a better oil for this truck, I ran it in my 03 for the two years I had it as well.

I have been running the 15-40 for the last 2-1/2 years year round. The winters have not gotten anywhere cold enough for me to worry about the weight giving me a hard time. I have been thinking about going to 20-50 for the summer. Doing the slow grind high traffic low speed grind in the city can be brutal. hell last weekend it took me close to 3 hours to go 26 miles. when it gets 98 outside and high humidity I am thinking that the extra weight may not hurt.
