royal purple is expensive, but a good oil. i usually buy Castrol or Mobile 1.Originally Posted by 04GTP

I have been using full synthetic Q power for the last 2 years. I usually add the lucas full synthetic additive. My last oil change I went to royal purple because of the speed channel special when they dynoed after the royal purple was added. I have heard all good about it so I decided to try it.

Purple is good no doubt, but I have been using Mobil 1 Full Syn since it came out back in the day. I used it for 5 years on my only GP GT and now on my GP GTX with no issues, and you save a good chunk of change in the process.

I have been told that you want to have 30 - 40k miles on the engine before switching to synthetic cause it takes a long time for the rings to wear in on newer motors, but use your own judgment on that....
I've ran Mobil 1 for the last 2 years no problems.... It does seem a little quieter of an engine with the synthetic, but that is not a fact, just my opinion

Im not trying to start anything but I just want to point out that there are cars that come from the factory pre-filled with synthetic motor oil, as do a good number of European vehicles. Synthetics do not really hamper the break in of an engine.
The only reason that you would want to delay using synthetics in a new vehicle is because on the factory fill, you will get a lot of contamination and leaching of gaskets and so forth and you want to get that factory fill out of there pretty quickly. This goes for the tranny too to some degree, Trannyman would be a better source on that. But for you with new trucks and so forth, dont forget about the differentials and transfer cases also that break in.
If you do an oil analysis on a new vehicle you will see a significant spike in wear metals along with silicone. This will level out over time. But you want to do your break on the factory fill and perhaps run one complete oil change interval on whatever fluid is recommended by the factory then after that you can switch over to what you want to use. If you switch over to higher cost synthetics too early, you'll just have to change it out long before its time because of the break in contamination, but it doesnt really hamper the break in process.

synthetic is good, but, the benefits don't offset the cost, in my opinion; especially for a DD. some good info.... Motor Oil Myths and Facts

I run royal purple in my car, and I love it because I have seen just a slight increase in gas milage.

Well if you are driving all highway or mostly highway for those 30 minutes, then you are getting the oil up to temperature for a sufficient amount of time to evaporate any fuel and moisture contamination. Short trip driving is basically any thing less than a few miles in length (10 miles is the cut off I believe) and involves several stop and go maneuvers.
Basically you want to drive long enough to get the oil up to operating temperature, then drive an additional 10 - 15 minutes to give time for any fuel contamination and moisture to evaporate.
Ever wonder why highway miles are so much better on a vehicle. This is one of the reasons. The oil gets up to temp, evaporates out moisture and fuel and maintains a steady flow through the filter to keep the contaminants in check so that when the motor is finally shut down there is less in the oil to accelerate degradation of the oil. This is also why, even with conventional oil, you can go longer between oil changes with predominantly highway driving. The oil stays cleaner and the cleaner you keep a motor oil the longer it will last.

very good info, I am glad my drive is as long as it is now. In fact I have often wondered why highway miles are considered better, granted I know some of the reasons why, but had no clue about the oil being part of that.

Good info Scotty. I may go back to RP then. Wise Speed Shop is sort of on my way home from work and they are/were the cheapest around on RP.

Weird thing is they carry a large selection of Royal Purple products, but I've never seen it on their site.

I have heard good things about Royal Purple, but I personally use Mobil 1.
03-18-2008
I get mine at the local Advance, but still $7 a quart

I use Royal Purple. I too noticed better MPG and a slightly cooler engine as a result. As a matter of fact, it takes a while to warm up idling even if its warm outside (t-stat is good, brand new in fact). That's a true indication to better lubrication.
Scotty has recently talked me into oil analysis which I will be performing sometime soon to see how my engine is feeling.

I have been on mobil one since day 1 on my 99.

Im a big valvoline fan. My 93 grand am with the 3.3L V6 (miss that motor) loved valvoline. I tried about every regular oil in that car and for some reason it ran quieter and got better mpg with valvoline. Right when i got my car I got an oil change with regular valvoline . next oil change same oil then lucas oil supplement. oil change after that switched to valvoline synthetic and been there since.
