Mobil 1 Users

[Red Diamond]

For those who use Mobil 1, check your local O'Reiley's. I just picked up a six pack of 15W-50 for $4.99 a quart, $2.50 below the $7.49 regular price. Will be at this price until the 28Th.

I found this test, Mobile1 vs Royal Purple Racing

Honda CR 450 (built on the basis of CB450 CB 500T frame and engine).

To measure the temperature of the engine we used a Fluke 62 Mini infrared thermometer, which was pointed out (laserbeam) 3 different places on the engine:
1: Right side - exhaust
2: In front of the engine block at the height of the crankshaft
3: Behind the engine block level with the gear box.


We used Mobil 1 Racing 10-40W oil and Royal Purple Racing oil
We set up the table, noting the time and completed 25 laps on the track. After every 5 lap, we stopped the bike in pits area and measured motor temperature (with the engine running) before we drove out to the 5 new laps. This took about 30 minutes, including temperature measurements. We tried to gander, and thus maintain consistent lap times under both tests.  After 25-laps the motorcycle was run directly on the Dyno, where we completed a run of 3 draws with measurement of horsepower / torque.

Then we stopped the engine, we drained the Mobil 1 oil, oil filter changed again and poured the Royal Purple Racing 41 oil. Then, the entire test program with 5 X 5 rounds out of the temperature measurements and a new bench execution carried out again.

The effects measured on the rear wheel increased by 1.94 hp (4%), from about 46.87 to 48.81 hp. Torque increased accordingly by the use of Royal Purple Racing 41

The most important was, however, that the maximum measured motor temperature measured on the engine block (front), fell by over 15 degrees Celsius after the test with Royal Purple Racing 41 synthetic oil!

Max temperature measured in front of the engine block of Mobil 1 Racing: 130.8 degrees C

Max temperature measured in front of the engine block of Royal Purple Racing: 115.0 degrees C

There is reason to believe that the friction between the engine's moving parts is reduced significantly, thereby lowering the engine temperature. Less friction and less heat generation increases the power and torque.

Always appreciate your research Dag. Thanks for the stats. Dave

As I have always said and lived Royal Purple RULES 

Thanks Dag

[Wildman]

Exellent data.
Is the Royal Purple formulated to run in a motorcycle ie. transmission and clutch wear and slippage?

[roboto65]

Yes

Is this an air cooled engine?

Agree, but aren't air cooled engines designed to run at higher temp thus sealing better (rings/cylinders) with the metal expansions and such?  On this test it is a significant 60 degF difference.

However according to the dyno I guess a bit more blowby is well compensated by the less friction inside the engine.

What temps are the Valks supposed to run? 
Personally I could go for a cooler running engine on these 100+ deg Texas summer days!!

[Dag]

I sent th Norwegian agent a email with quetions about temperature, transmission noice, clutch wear and slippage.

Here is the answer:

Hello Dag,

Thank you for your interest in Royal Purple oil.

I think you will find the Royal Purple oil very good in solving the problems you mention.
I will give you an oil change free. Send me your address and I will ship you one gallon.
I`m sure you will be satisfied.

I said "yes thank you"...
I have a infrared thermometer and will check the temperature several places on the engine with the Valvoline Oil I`m running now and compare it with the RP oil.
The Valvoline oil is my best choice so far regarding lubricating properties, cleaning the engine and gearbox sound.
I also have the ability to take a sample of the oil at the next oil change to see how much soot and impurities it has taken from the engine and how the lubricating properties are at our laboratory.

[John Schmidt]

Sounds interesting and worth a try. What's the cost, is it comparable to Mobil 1?

[Dag]

About 8 us dollars a quart

DAG is this the rp motorcycle oil or the car oil?

We talked about a Motorcycle Racing Oil. They have many different Racing oils, so I sent him a email asking for the exact description of the oil they recommend. I`ll post the answer tomorrow.

[KerryNolan]

How do these oils measure up to Amsoil?

This is from my correspondence asking which to use in the Valkyrie.....


"Our first recommendation for your Valkyrie is Royal Purple Max Cycle 10W-40 (part #01315, quart bottle).  A more convenient alternative would be Royal Purple SAE 10W-40 (part #01140, quart bottle).  Both of these oils will perform great in your engine and with your wet clutch.  However, the Max Cycle oils are more robust formulations and contain a higher level of anti-wear additive compared to our SAE oils.  If you do decide to try Royal Purple in your bike, I, too, would be very interested in your results.  Right now I am in contact with two gentlemen trying our products in a stock BMW touring bike and an air-cooled Yamaha with a centrifugal clutch. "

Well if anyone is in the Houston area and would like a tour I know who to call I took a tour of there plant in Porter,Texas very cool learned lots of interesting things like they package and ship it over seas under a different name well another company buys it from them and they package it under there name.
It has a different smell and always has to me he said thats the special ingredient 
also learned about their grease. They also are making filters now and yes there is one for the Valk I have it on my bike right now and yes it is purple 

I have been using Royal Purple in my Cars, Bikes and other implements of destruction for years and what I use is NOT motorcycle specific but has NEVER given me any problems.

Every lube in my Valk is Royal Purple from the Engine to the pumpkin.

[ricoman]

Dag,
what Valvoline are you using?
I wonder if anyone has experience with Castrol GTX?

[Dag]

Dag,

I use Valvoline DuraBlend 10W40

thats the oil i ve used in the dodge 2500 van since day one , it has 142 k and puuuuuurrrrs.

[Red Diamond]

I think I have learned my lesson on oil, cheap or expensive, I'll try not to mention oil again.

For what it's worth, thanks for the posting. I did go and pick up 4 quarts of the Mobil 1 so thanks for the heads up .... pretty good price 

[Red Diamond]

You're quite welcome, glad to help.

Oh come now Red Diamond! That's no fun~~~~ These guys live for provocation and crave the opportunity to speak their learned minds. We have a lot of guys on the VRCC Tech Board who should be Doctors of Valkology. You live and you learn with these bikes. The good part though, is that if you have a problem, somebody here has seen it, figured it all out and dealt with it in one way or another. Real Value for your money if you ask me.

I use Mobil 1 T4 Racing Oil in my bike and love the stuff. My bike runs smoother, quieter, cooler and when I drain the oil at 5,000 miles it's still relatively clean as compared to any other oil that I've tried in my engine. I don't have one of the fancy dan digital temperature instruments that Dag has, but I can tell it's cooler to ride than what it once was in 100 F heat, which is fast approaching. I tried the Amsoil and liked it, but it was black when I drained it out of my engine.... no good! YMMV Ride Safely!

[Red Diamond]

You are dead on NiteRider, I'll take my stick out of the mud and put some sugar back into the punch. Personally I don't know why these other fellows use Amsoil, Rotella T5 or T6 and car tires on their bikes. We  both know Mobil 1 and Dunlop motorcycle tires are the best out there.

[Mr.BubblesVRCCDS0008]

Oh now wait a minute you just stepped on alot toes there. My car cruise control controls mine mobil 1 car oil lubed engine just right to keep a control of my car tires rpms.Just kidding.  no flames please just a joke.

[NITRO]

Just FYI: I noticed in the paper this morning that Farm & Fleet has mobil 1 for $5.69/qt, plus you get $12 back by mail if you buy 5 quarts.

Just fanning the flames a bit Mr. B, haven't met you yet, but I'm sure it will happen. I think you are a shift worker, been there, done that. Ride Safely.

[Mr.BubblesVRCCDS0008]

I'm sure we'll get to meet soon. I was just fooling arround.I was just stirring to pot to get some most postings.

[OverdueBill]

Thanks for the information.  I picked up 8 quarts today.

[Dag]

Sorry I highjacked this thread with this nonsense 

Tis is from my website:
There are very good automotive motor oils that some of my friends use in their motorcycle, while others wouldn't even THINK of putting something in their engines that didn't say clearly on the label that is was created specifically for motorcycles. Some of my friends are completely sold on the fact that synthetic motorcycle oil doesn't break down as quickly and wouldn't use anything else - in their motorcycles. Others choose to stick with the dinosaur oil. As long as you choose a top-of-the-line oil product that meets the specs for your engine, the choice is yours.

I noticed that Mobil 1 also has MC specific oil on their list .... is it much different than the silver cap (non-energy conserving) that everyone has been buying ???

Mobil 1 Racing 4T 10W-40 is my oil of choice.

Just switched {at 100K no less!} to Mobil 1 10W40 4T synthetic from Rotella 5W40 synthetic in my Valk & I feel it makes less gear whine & shifts smoother too. Maybe it's just in my head but at next oil change I'm going to switch Kim's Valk also.
BTW the Mobil 1 does cost right at double what the Rotella does.
So far, so good!
