Soooooo, on stock oil I was getting right at 11.9 MPG. Swapped to royal purple a few weeks ago, ran 3 tanks of gas, and it jumped to 13.2 MPG all 3 tanks. Same driving, nothing else done to the truck, and these calculations are all done on paper, not the evic. Anyone else experience the same? I'm simply stunned. Can't frigggin wait for a tuner!!!

That's pretty cool. However, if the temperature where you lived has gone up in the last few weeks since you changed over, you have to take that into account also.

My mileage has also gained 2-3 MPG in the last three or four weeks from the warmer temps.

I'm definitely getting better mileage since I switched to Royal Purple. I'm up to 16.3 average and that's after sitting in Philly traffic for over two hours stop and go on Sunday. It was up over 17 before that. I have about 3000 miles on the R/P and about 21,000 on the truck. I'm sure the warmer weather has something to do with it but I had it in the warm last year and still didn't do this good.

Changed to Royal Purple at 3900 miles. Truck currently has around 4900.

And I don't think weather has toooo much to do with it. STL is notorious for odd weather. Last month it was 80 on a Monday and snowed 13" the day after.

Either way, I still can't believe it. RP is DA ****, and I'm pretty sure that filter is bulletproof.

You're opening a bag of worms w this question. Personally, I wanted to put 5000 miles on the stock oil, but after 3900 I gave in.

Some say change it right away, other say change it at 1000 with dino oil then again at 3000 w syn. It's really just what u feel comfortable w.

The refineries are switching from winter blend to summer blend around this time of year. The summer blend usually results in a few more MPG.

I didn't change a thing and am getting better gas mileage all within the past few weeks. Switching to RP from mobil 1 thanks to the sales brought to my attention my yo nadz.

But yea I have heard of different gasoline blends for summer and winter.

Matt what kind of MPGs are you getting around here?
I think my dad is only getting 11-12 mpg in his bone stock '11 hemi but he only drives 6.5 miles to work and there's 11 stop signs or more
