   This review is from: Royal Purple 31140 HPS 10W-40 High Performance Street Synthetic Motor Oil with Synerlec – 1 Quart Bottle (Automotive)

   So I have been a long time loyal user of Royal purple motor oils. This new oil recently came out from them so I HAD to try it. The only difference between this oil and the normal SAE Royal Purple is the addition of Synerlec which is used as a more powerful solvent to remove any deposits within the engine left over from inferior oils. I use it on both my Car and Motorcycle (2003 ZX-6R) because it contains NO FRICTION MODIFIERS! I confirmed this with a tech who works at royal purple so fear not this oil is 100% WET CLUTCH SAFE!!!!! I recommend this to anyone who want to get the most out of their high performance engines!

   This review is from: Royal Purple 32140 HPS 10W-40 High Performance Street Synthetic Motor Oil with Synerlec – 12 Quart Jug (Automotive)

   The engine seems to run cooler and quieter with slick gear shifting. I usually use Mobil 1 4T for my Triumph motorcycles, but thought I would try this. No complaints so far. Buying the bulk pack made it even cheaper than the Mobil 1 4T.
   The ‘proof’ will only be known 50000 miles from now, but it appears to work as designed.

   This review is from: Royal Purple (36140-6PK) HPS 10W-40 Synthetic Motor Oil with Synerlec Additive Technology – 1 Quart Bottle, (Case of 6) (Automotive)

   My almost new car ran smoother with this oil in the pan. This is my first use of RP oil and so far I can’t complain. They didn’t have an exact match for my car’s required weight, so their tech support recommended this oil. It’s lighter that the manufacturer called for but the RP folks said it was superior to the oem oil, which is what I’d expect them to say. The engine seems to start and idle easier/smoother than with the oem oil. The car seems to hold RPM longer between gears when shifting. No new engine noises/clatter by going with this lighter oil. Still quiet on start up. I’ll be trying it in other cars as well as their oil changes come due.
