Default Royal Purple

I'm about 3K miles from my next oil change.

I already run Mobile one Synthetic. Is it a good idea to switch to Royal Purple and to take advantage of the rest of their product line?

Engine, T-case, AT, and Diffs?

What do you think? Some of the most well known engine buiders have switched over to it. (Even my Dad for his stock cars, supermodified engines).

Pop said it couldn't hurt, but thought GM might have something to say about it.

GM can't void the warranty if the fluids meet their spec. But how would they know ... unless RP actually is purple. (Is it?) Mobil1 meets the H3's GM4718M engine oil spec. Don't know if RP does.

For the transmission, it probably needs to meet Dexron III-E or III-H (there's a difference and again Mobil1 ATF meets both). The diffs already contain synthetic oil so aftermarket synthetics probably wouldn't hurt but wouldn't necessarily help

Actually it will help swapping the OEM syn in the diffs to a better syn fluid. I switched mine to Redline in my H2 and it's much smoother driving than b4. Weather got too bad out to do the front diff yet, but it's on my list

I would suggest looking at your manual and read the print on the dipstick to see if your tranny requires Dex III or VI (6) before putting syn in the tranny. If it requires Dex III, then go for it but I would suggest a complete tranny flush and new filter. No company makes syn ATF to meet the requirements of Dex VI (6) at this time as it's a lower viscosity fluid!!! If yours requires Dex 6, then suggest staying with GM Dex 6 OEM fluid.

Just dropping the pan and changing the filter will only get have half the fluid out and wont get it out of the torque converter unless you do the flush.

Either way, I would do the Syn in the transfer case for sure as the requirement for the TC is more than likely just Dex III ATF.

Doing the diffs is optional, but the RP fluid is much better than the OEM syn that's in there. I would go ahead and change both front & rear at about 20-25k miles to the RP if it were mine.

My old roommate used to swear by RP. I personally havn't used RP. I have used Amsoil in my old truck and loved it. I'll be making the swap over to syn. soon. Just need to let the motor break in a little longer. Also found some links.

HummBebe, go to their website and watch the videos, and read the articles. I use Royal Purple in everything I own, including my chainsaws and industrial sized weedwhackers. I've got it in my Dmax, my tractor, and even my quad. It's really really good stuff and it's dyno proven to make the difference (Hot Rod magazine did the testing, the videos on their website) http://www.synerlec.com/video/video.html

I started using it on my own because I use it in our equipment at work. (I'm the lube guru) It was a real eye opener to see it drop one of our compressor's operating temperatures 25 degrees. It's extended the run times on our 4kv feedwater pump motors to ridiculously long intervals. It's the real deal and well worth the price. I get mine shipped from this guy: http://www.karlracing.com/html/royal_purple.html

Another way RP helps is that you have a knock sensor that affects the engine's output. RP products (and it's Purple Ice coolant additive) lets the engine run cooler at max load. Again, I've seen the cooler operating temperatures on power plant equipment where I have a lot more monitoring devices installed so I believe to be the same in their engine lubricants also. Yeah, there's a thermostat, but before I started using the RP in my Hummer, it did move above the where the thermostat usually keeps it, on RP, it doesn't.

If you have ANY questions about what product to use where, the guys at Royal Purple's customer line will help in a minute. 888-382-6300.

You'll hear or read many people saying it's a waste of money and that it's not worth it. Bull, dynos don't lie. People spend hundreds of dollars on exhausts, intakes, filters, chips, you name it, why not spend a little extra and give that I5 some extra lovin'? The added benefit of protecting your engine that much better is another benefit. As long as the oil change intervals are, the cost of RP is inconsequential, particularly considering the aforementioned benefits and improvements.
