From a former CAM2 saleman, you CR comments above are accurate. I had color copies of that article printed so I could leave them with potential new distributors. It was a compelling story. I will add toWhite Ram'scomments; the report mesured wear on critical engine parts after being run something like 600,000 miles (many taxi cabs go 1 million miles). CR reported that they didn't find any significant difference in brands provide that they were ILSAC approved and carried SJ specifications (current API rating in 1999 or there abouts). As you may know, ILSAC is the rating for fuel saving oils (at the time 5W-30 and 10W-30 only). What was ment by fuel saving oils isthat you andI wouldn't see MPG increases as they were fractons of a MPG, however, the nation as a whole would benefit from the fuel saving characteristics of the thiner motor oils if everyone used them. Like White Ram stated, CR suggested to buy the least expensive oil that carried the ILSAC and SJ ratings because you would not experience a difference in engine wear. I will say that the CR report did not measure things like HP gains and sludge differences -both things that quality synthetics excell in.

 

well what about the thing on trucks about royal purple being an 11hp oil change?

 

royal purple 10-w30... with napa gold filters..

as for that hp increase.. i wouldn't have believed it if i hadn't seen them do it on the show. course it could be "magic" but i'm more inclined to believe it. but you have to remember the vehicle, and they also did the transmission, and also the diff oils.

so between all those places i'm not too surprised that they found a better way to lubricate the gears and reduce the parasitic friction losses in there.

using synthetic over dino is really up to you. i've heard sometimes older engines don't like the synthetic as it will leak through the seals (smaller particles), but then again it does have some good qualities for those same high mile engines. i don't know for sure as i've just hit the 50,000 mile mark with my 01.

putting the royal purple oil in did seem to have a small effect on the upper end, but i wouldn't say all that much. you'll probably find more horsepower and torque by replacing the transmission fluid than you will by doing the engine oil.

 

How is it you are spending $60 for an oil change? It costs me $23.67 for a 5 quart jug of Mobil 1 at Wally World and $3.97 for a Purolator filter at Advance Auto...= $27.64. Which is what I used to pay a local oil change place to do it with cheap oil - and then I found out they weren't even changing the filter (I marked the one that was on it) Since then I have done my own. Takes me 10 minutes. If you are paying someone $60 to change it and put synthetic in it - how do you even know they are REALLY putting synthetic in it?? I've heard and seenlots of horror stories from oil change places...the only thing that I allow to go there is my son's Furd and that's because the way it's designed it dumps oil all over the place when you remove the filter.....

I know of two instances where Fram filters came apart or split and fried a motor. I also used them for a long time myself with no issues. After I read that test I decided that the guys who did it know a whole lot more than I do and it was no problem to change brands to one that rated better in their test. So - I switched. I switched to synthetic oil about 30k miles ago and noticed a difference right away. The motor just runs better and smoother. Hard to describe - you guys that have owned and worked on your trucks for a long time know what I mean - It just runs better!
I figure for 10 minutes of my time every 6 or 7 weeks and the same money it would cost to go to whatever lube store and not get good stuff - I'll take care of my truck myself.....

 

i am sticking to my pennzoil it works for me and the fram filter filters the oil so im good.

 

yea i always change my own oil matter of fact i did it today castrol gtx and a fram filter only because there was a sale it was only 11.99 but next time im prolly gonna use gtx with the purolator filter

 

I bought some oil for my truck today and got 5quarts of Royal Purple with a can of brake cleaner which I think was $2.39 and my total came to around $41. I then bought a Pure One filter and that was I think around $6. I like the RP oil and use it in everything other than my Chevy and I would have used it in that but they were sold out of the kind I needed so I got Mobil 1 which was only $1 cheaper per quart. I'm kind of getting tired of spending $45 on a oil change though and thinking about going back to regular oil in my older Honda atleast and maybe the truck too. It's getting too expensive but I do like the RP oil

 

I use Royal Purple in my trucks.

 

RP is good stuff but in now way is it worth $6 a qt. Waste of money to fun it every time imo

 

It's like $7 something a quart here almost 8.
