## Questions & Answers

**Q: Always use luca 80w-90 in ford ranger 2.3l, 7.5" rear diff.  wanted to try this.  any issues with it being a 75w vs 80w?  is this better than lucas?**
A: I use the royal purple 75w-90 in my RAM 2500 differential. My differential is made by American Axle Manufacturing and I talked with one of their mechanical engineers who said the viscosity requirement is determined by several criteria with ambient and operating temperature being big determinants. I live in a warm climate so he said I could use a heavier weight oil. With that knowledge I don't believe there is a big enough difference between the 75 and 80 other the better lubricity at lower ambient and operating temperature. He did recommend amsoil but said the royal purple is just as good.

**Q: I have graphite/ composite  synchronizers in my  transmission , will they be damaged by the use of  anything other than the "Castrol syntorque" recom**
A: I've had the best experience with Redline MT90 in manual transmissions. RP was not working well with syncros (grinding gears when shifting).

**Q: I know that the product description says that it is not for use in wet clutch systems, but will it be okay for use in motorcycle final gear (shaft)**
A: Will be fine as a motorcycle final gear oil. I use this product in two BMW motorcycles, a BMW R1150RT and a R1200S, as a final drive oil and also as the transmission oil.

**Q: Will it work in a bmw x-3 transfer case, the manufacturer calls for their fluid # TF0870?**
A: No. Use the BMW fluid.

### ⭐⭐⭐⭐⭐ Awesome product
*by  on Reviewed in Canada 30 March 2024*

I used this on my skidoo gear case. I always use this product for my machines. It does the job and I have never had an issue when I do use this. Others are definitely cheaper, but when your on a trail 50 km from home it’s nice to know this isn’t going to be the reason you have to walk home.

### ⭐⭐⭐⭐⭐ Stunning fuel economy improvement
*by  on Reviewed in the United States 21 April 2014*

I used this stuff to replace the transfer case and differential oil in my 1999 Toyota Land Cruiser, which has a monster V8 engine and previously recorded a best fuel economy of 14 mpg highway. I checked fuel economy carefully over many trips on the highway, always driving conservatively at the speed limit, 65 mph in NY. So I'm very confident in the 14 mpg and that's best case driving. Town and stop-and-go driving was lower. Also the 14 mpg was measured after a recent engine oil and filter change with Mobil 1 Synthetic. Anyway, I'm pretty sure the transfer and diff oil was never changed by the previous owner, based on the condition of the drain screws and the fact that something resembling black pudding sludge dripped out during the draining process. The transfer case took about 4 quarts and the diff about 5 quarts. I "wasted" about one full quart during the oil change trying to flush out the gears by continuing to pump in more fluid during even after it started leaking from the upper fill hole. This did seem to cause a few squirts of additional sludge to come out through the drain. After the change I immediately noticed that the vehicle seemed a little quieter and smoother, it was a barely perceptible change but I'm pretty in tune with the noises this LC makes, and noticed a definite lower sound from the drive train, in fact it was very quiet overall. The big surprise was the gas economy, though. Halfway through the trip, which is about 100 miles and route I drive fairly regularly, I knew the gas mileage was better than before. Upon returning home and hitting the first gas station off the highway, I was amazed to find that my fuel economy went from 14 mpg to 17.42 mpg, an unbelievable 24% improvement. Nothing else changed with the vehicle, same driving style, same gas, etc. The only variable that changed was the use of Royal Purple. Assuming this continues, my fuel range is increased from approx. 280 mi/tank to about 348 mi/tank. This equates to a savings of roughly $15.50 per tank, or for city driving probably around $10/tank. So the whole load of oil will pay for itself fairly quickly. My cost per mile dropped from $0.30 to $0.23. I'm very impressed with this oil, so far it is one of the best things I have done for this vehicle. I will use it in my other car for sure. Expensive but definitely worth the price.
