the wal-mart i work at carries Royal Purple, and Accel....

 

so i went and spent the $111 on the motor oil and rear end fluid today, along with a oil filter and rtv lol, so looks like i have a project this week or next weekend to do lol. i hope its worth it lol

 

It's worth the switch. Synthetic doesn't break down as fast as conventional. Using Mobil1 and lovin' it!

 

RP is comparable to Amsoil so I'll give you a little Amsoil data;

Last 4 fillups running stock differential fluid and Mobil1 oil:

217 Miles / 14.25 Gallons = 15.22 MPG (~ 1/2 City / 1/2 Highway)
342 Miles / 22.15 Gallons = 15.44 MPG (~ 1/2 City / 1/2 Highway)
184 Miles / 11.43 Gallons = 16.09 MPG (~ 1/3 City / 2/3 Highway)
212 Miles / 12.85 Gallons = 16.50 MPG (Pretty much all Highway)

This comes from my work log, I have to fill up and record everything on every trip.... Anyway, switched to Amsoil Differential fluid and Engine Oil at the same time, however only had 2 logged fillups before I got my Edge programmer:

285 Miles / 16.44 Gallons = 17.33 MPG (~ 1/3 City / 2/3 Highway)
141 Miles / 7.74 Gallons = 18.21 MPG (All Highway)

I was happy with what I saw, and definantly think it's worth the extra money... I got my programmer after that and have since broken 20 MPG's on all highway fillups... I think I've tapped all the mileage I'm going to get out of my truck....

 

replaced the oil and rear end fluidwith rpabout a week ago and so far so good... seems to be running a bit smoother now. love it thanks for the help guys

 

i ahven't had a chance to switch the diffs and transfer case yet, but put Amsoil in the engine early last week. the tick it had is a lot quieter now, might even be gone cuz I don't notice it anymore.

 

me and my boss are ordering a case next week...both have it in our bikes and it helped out alot there! wish it cost about half as much tho

 

I'm looking at my next oil change switching the oil to Royal Purple and doing the same with the rear and maybe the tranny. I have a question about the tranny though. Since I only have 10,000 miles on the truck and it has a 6 speed manual will it do any good. If so is there a special type I need to order?

 

Overpriced and over rated.
