Rate this Entry
Well I had to have the truck inspected and I had the oil had the oil changed at the same time. I was going to go back to Mobil 1, but there was only $7 difference to stay will Royal Purple. I'm good til the next oil change and it only cost me $94.45! Oh well, oil is cheaper than PARTS!

    How many miles do you drive before you change the Royal Purple?

    I drive 12000 miles between complete oil changes. You drive 4000 miles and change the filter and add a quart or RP. So, every 4000 miles you change the filter and add a quart. I have seen a 1 to 1.5 mpg increase from Castrol GTX, but lat most .5mpg from Mobil 1.
