What a difference! My VTX 1800, vibrates less at all RPM's and shifts better. I'm also getting about 10 more miles per tank than I did with the stock Honda oil.
A good oil will just work. It will lubricate and protect. Most oil manufacturers create various grades of oils using different bases and techniques and they produce products that will do the job.
A fantastic oil will go beyond and Royal Purple does exactly that.
I am not an expert but I do know a thing or two about automotive mechanics. The area of lubrication fascinates me and from what I see on the internet, it fascinates many others as well. This is delightful as I was beginning to think that I was a freak! Perhaps I am and perhaps all of us are. Is it so bad to want what's best for your ki.......cars? Your cars! Yeah that's it, yeaaaah. Seee.
After building a supercharged vehicle, I became obsessed with making sure it was running in top shape. It was at the time, my only means of transportation. I started using Mobil 1 synthetic right away and for years, there was no problem. Mobil 1 is a perfect example of a good oil. It did it's job. I've always known about these so-called "high performance" engine oils out there such as Redline, Motul, AMSoil and Royal Purple. I figured that they were all just gimmicks because really, oil is oil right? Well I was wrong.
While shopping in Walmart, I noticed that they had cases of Royal Purple 10w30 for sale. I was there to pick up a case of Mobil 1 but the royal purple was there and it was only a few dollars more expensive. I figured, "why the hell not?". I brought it home and the next day, I changed my car's oil from Mobil 1 to Royal Purple. Now I forgot to mention that my oil changes, which I obviously do myself, happened every 3000-5000 miles and that I change the filter, every time. You can never be too careful with a forced induction car that wasn't meant to be forced to begin with.
Well when I started her up, I IMMEDIATELY noticed that there was a difference. What I noticed was quiet! Then I noticed how smooth the engine was running. It was just plain old special. After warming up I took her for a spin because that's what we do when we try new oils :). The butt-dyno was definitely telling me that the car was faster. She was definitely running stronger and smoother.
A few months ago, I decided to go back to Mobil 1 due to their formula changing (so I read). I wanted to give it another shot. After all was said and done, I went from a "fantastic oil" (Royal Purple) back to a "good oil" (Mobil 1)
Even though I knew I did not need to do it, I quickly swapped it out for some fresh new Purple :)
I tried using it in my little CRF150RB dirt bike but I didn't notice any differences. That bike is like a little bat outta hell. It does however, make a nice difference in my scooter. It is again, smoother, quieter and more powerful and with a scooter, every little bit helps.
In conclusion, in my personal experience and opinion, Royal Purple is just far beyond anything else that I've used.
Info:
Car 10w30:
Mobil 1 - Good
Royal Purple - Fantastic
Dirt Bike 15w40-20w50
AMSOil - Too happy to care
Motul - Having too much fun to give a rip
Royal Purple - Noticeable gains in yeeehawww but not with oil
Scooter: 10w30-10w40
Mobil 1 - Noticeable gain in speed, lower temperatures, and longer viscosity life over petroleum-based oil
Motul semi - Similar to Mobil 1
Motul ester - Similar to Mobil 1
Motul double - Slower more sluggish at first but once oil is HOT, performs exceptionally better than Motul or Mobil 1
Royal Purple - Performs similar to Motul double ester but seems to keep viscosity longer and has a quicker "warm-up"
AMSOil - AMSOil is also a fantastic oil however, it is in my opinion, slightly less than Royal Purple. It does the job well and keeps it's viscosity for a long time but it does so at a higher cost.
I hope this helps!
Oil is the life's blood for any car. The better the oil, the better the protection against metal to metal contact. My old Porsche 944 was part of a project covered in a natiojnal Porsche magazine and one of the things we did was change the rod bearings and experiment with top quality syntnetic oils. Usually, I use 15-50 Mobil 1 - it has always worked well for me. But my contacts who do a lot of track driving gave Royal Purple racing oils some high praise and I have to say that my experience has been very positive.
Oil pressure (before changing the rod bearings), at normal operating temperatures, was higher than with Mobil 1 (always a good thing on the track). Also, oil consumption was lower (on Mobil 1, I would use about 1/4 to 1/2 a quart per session of 6000 RPM running). On Royal Purple, it was 50% improved.
Also, I put their gear oil in the transmission and the change was even more dramatic. I am not sure what was in the transmission before the switch but immediately after the switch, shifting was much smoother. This was a revelation.
If you drive your car on the track, give this product a shot - it is a high quality synthetic motor oil.
