Has anyone tried Royal Purple? Is it worth it?

I get 13 -15 MPG just like the majority of the posts, as far as oil change 3000 -3500 used to be the norm when your oil pan held 5 qt. now days when you put 7 qt. in an engine you don't have to change as often. I use motorcraft 5w 20 and a purelator oil filter every 5k. Works for me

our 06 frontier gets 14mpg(33's, cai) and our 05 fx4 gets about 17 it seems. All city driving. funny how that worked out... haha

I'm using it! As for worth it, I can't say with 100% certainty. I noticed a 4 degree drop for daily driving in engine temp (196F -> 192F ) and that's about it. I have to admit that it was their advertising and results I've seen published in magazines that got me. I don't think you can go wrong with any full synthetic that meets oem standards and am looking forward to not changing my oil till June.

Fwiw, 7 quarts @ $9 = $63
K&N Filter @ $16= $79 total.

So it is VERY expensive compared to regular oil.

All stock.

I've been using 5W-20 Mobil 1 since truck was new, thinking about switching to the 0W-20 to see if mileage goes up any. Has anyone else tried this oil yet? Comments?


06 Screw 5.4L 3.73 rr 2wd 6.5ft bed. K & N aif filter, stock otherwise

5w-20 is already so thin!
Not sure how well the 0w-20 would dispense the heat and lube the block.
