Seat o the pants dynometer says royal purple oil n gear oil WILL increase horsepower. No actual proof but the bike just FEELS faster in 1st n 2nd gear. | ||

where do you get those pants?  | ||

I saw a program on TV, I think it was Hot Rod TV where they took a stock Mustang GT. They dynoed it. Changed all the fluids to Royal Purple and gained 6 HP. That being said, on a 300 HP engine that is a small gain. On a 75 hp engine the gain would be even less. It did show me that it is probably pretty good oil. | ||

i have one of those butt dyno to they work great!  | ||

I think anytime you do something different to a bike or any vehicle it seems to make a difference. I have waxed a car before and I would swear it was faster. I do believe that a high quality oil will make any vehicle a little faster. I know when I started using Mobil 1 in my vehicles you could tell the engine just spun up quicker. Now that I am using Amsoil it seems like I have moved up another notch. So yes I really think it can make a difference. | ||
| Buelltroll |
Amsoil is what I took out. YOU try it. Switch all your fluid to royal purple. I'll bet ya a dollar you CAN feel it spinning up faster. Plus it just didn't seem to be as strained at 130mph. | ||
| Alexfiggy |
what did you use 20/50?how about the tranny | ||

You nailed it, I'm calling BS. On the other hand, I *did* see a test where they had dyno proven horsepower gains just by switching to Royal Purple. Of course, they switched from a traditional weight 10w30 or 20w50 to some oddball zero weight oil, and the gains were in the range of one horsepower. Seriously though, there's no way you gained a noticeable amount of horsepower by changing oil. | ||

we were using synthetic oil in our drag cars over 20 years ago, and it is definitely worth a little e.t. and mph. Not a large gain, but noticeable and repeatable. Add a bit of nitro to your crankcase, and you'll REALLY notice a difference!  | ||

I can tell you for a FACT, that putting Armor-All on your Buell seat will result in a much higher "hinnie dyno" horsepower reading, and it is cheaper than any synthetic oil change too.  | ||

I know of two experiments where a bike was dyno'ed and oil changed to synthetic, redyno'ed and picked up 1 to 2 hp MB | ||
| Buelltroll |
I'm tellin ya ALL switch your fluids to royal purple and THEN tell me you don't feel a difference. | ||

BuellTroll, Way back when I used to care about 1 or 2 horsepower I tried all kinds of things on my F2 to squeeze out horseys. It was easy because my buddy had a dyno. Royal Purple made ZERO difference. The big difference was with almost any systhetic. A whopping .5hp increase!! Damm I miss those evenings, drinking beer and spoolling out bikes. | ||
| Buellin_ri |
I think I'll side with Skyguy on this one. I don't really feel that 1 or 2hp is a big deal. | ||
| Tommy_k |
I'll take that bet... Just changed it to RP... Nope, don't feel it... You can Paypal that dollar to my email! TK | ||

Back in the early 90's, I had some involvement in the SCCA Racetruck series. Because the series was sponsored by Shell, all trucks were required to use Shell lubricants at all times. I know of a team who paid for extensive engine dyno testing and found that Kendall oil repeatedly produced higher horsepower than any other available oil. So, when the Shell folks would drop off a new case of oil at the track, this team would have one of their go-fers dump out all the Shell oil and re-fill the bottles with Kendall. That way, anyone touring the paddock while oil was being added to that team's trucks would see "Shell" oil going in. | ||

Let's look at this logically. Lubricants do not increase horsepower. A thinner lubricant will allow an engine to rev quicker, however, 6500 RPM is the same regardless of what oil you use. Horsepower is gained by increasing displacement, increasing the bang in the combustion chamber, increasing the revs of the engine, or some or all of the above together. Shows that dyno the same car with different lubricants to reveal a gain in power is the equivalent of David Copperfield convincing the world that he really made the Statue of Liberty disappear. It's all smoke & mirrors, so be careful! Chris | ||

You're right: "Lubricants do not increase horsepower." What they can do is decrease friction. Let's look at this from an extreme point of view. Assuming the engine would actually run, which engine would have less internal drag friction -- an engine with tar running through it or an engine with zero weight racing oil? The engine with tar inside would "use up" horsepower overcoming the increased friction. The right oil can free up horsepower that might otherwise be spent just turning the motor itself. | ||

The Sport Rider magazine several years ago on MC oils DID show a dyno increase when switching from DINO oil to RACING SYNTHETIC. To be fair, they also changed viscosity to a lighter oil and acknowledged that this might not be a good strategy for street use. Seems to me that less friction means more HP and syn oil certainly seems to allow for greater MPG so I say, go for it. | ||

Here is a link to the thread in the KV where I posted the link to that article: http://www.badweatherbikers.com/buell/messages/3842/108747.html?1139718836 So it can free up (not add) HP. But, to anybody who thinks they can feel 2 hp or who thinks their butt dyno is accurate- all I can say is do a couple of hundred runs on the drag strip and report back how "accurate" your butt dyno is! I promise your a$$ is lying (as a$$'s are prone to do!)! | ||

here is a butt dyno guarantee...drain your oil and don't put any back in its place. Then fire it up and take off. You are guaranteed to quickly notice a 100% hp loss, and you will feel that with your "butt dyno" and you will have to use foot hp to get back. also, good one Aldaytona | ||

i will add that i changed to mobil one vtwin synthetic and changed tranny fluid to mobil one 15/70 synthetic and i did notice the changing of gears feels much better and smoother. But, as far as more power goes I think that is a "placebo effect", just like when they are doing testing for new prescription drugs and the person getting a placebo says they can tell it is working and that they feel much better. | ||

I'll bet you a dollar that if you armor your tires you'll sh@t your pants.  | ||

Lower lubricant viscosity is what will improve power output. It will also reduce film thickness. Careful with that. I understand that the AMA Buell racers run a 30W rated synthetic oil. Got that during Daytona 2001. Not sure if it still holds true today or not. | ||
| Buellin_ri |
I look for engine protection in my motor oils not so much horsepower output. On a track for only a few miles at a constant rpm, may not demand as much, as stop light to stop light in the summer. I do hear good things about Royal Purple. But I like Mobil 1. I'm sure the differences between the two are like splitting hairs, but its a personal preference. | ||
| Fullpower |
there is no SAE specification for "30W" there are exactly five winter specifications for motor oil, they are in order: 0W, 5W, 10W, 15W, and finally 20W. these are all measured at the temperature of ZERO degrees Fahrenheit. the "W" stands for "Winter" and is not intended, nor properly used as an abbreviation for the commonly misused term "Weight" when trying to discuss the viscosity of a lubricant. Thank you for listening. dean. | ||

Donny just LOOKS much faster in his royal purple underwear. | ||
| Blake |
You are right. My bad. I meant xxW30 like a 0W30 oil. I used "W" as an abbreviation of "weight." Forgive my transgression. | ||
| Chance |
Yeah, I tried the switch, and my gain was like twenty five horsepower...I switched from my XB to an R1 |
