Royal Purple?

[drturbo]

For the past 4 years that I jave owned my 88 ranger 2.9, I have tried out Sunoco syntethic 5-40 in winter and 20-50 mineral in summertime.
I have also ran Castrol, and several other brands.

The only differense I have discovered, is that 5-40 is to thin when pulling heavy stuff in the summer, AND 20-50 is to heavy is too heavy for winter...

Other that that, anything I run provides rattlefree engines under normal operations.
Engine mileage is 216000kms, and I change oil roughly 3 times a year.

ok so i put the royal purple in my truck with the mobil1 filter and it did make a noticeable difference. the main thing i noticed it the compression in the motor and the more quiet idle of the motor. Now we shall see how long this product holds up. it is about $7.69 a quart here and then the filter was $13 so hopefully this oil holds up to its reputation. I would recommend this oil. It is the lower weight they recommend for the summer. i think its 5w-30.

you can just switch right over. the only real "complaint" i have ever heard when switching is the possibility of acquiring leaks. However one must ask was that particular seal or gasket ready to start leaking anyway? It is my understanding from an individual that over the years have come to trust (he is a mechanical engineer) Royal purple was designed initially for heavy use stationary equipment because the companies were tired of changing oil so often. and on top of that the week end hot rodding show "muscle car" did a chassis dyno before and after Royal Purple and the numbers do not lie increase in R.W.H.P.. plus lower emissions. and on another note e3 spark plugs were also tested and h.p went up emissions down and fuel economy went up.

Be careful Basket... That dude will be getting you to drink the coolaide next!
All them things you posted are IMPOSSIBLE! If the plug you have now is sparking then NO PLUG can make a difference! End of story..one spark is just as good as any other spark!! It isn't the spark that gives all them things... It is the fuel. You need another guy to give you advice.

I think they proved that wrong on Horse Power TV. They dino'd an LS V8 with the e3 plugs and the HP went up 7hp at the crank and lowered fuel consumption by 10% and lowered emissions by 4%...... as tested with the EPA's own sensor equipment and evaluated by an independent lab............

 

[Cyberbeer]

People think synthetic oil causes their engine to leak because it cleans the sludge from dino oil from around the seals. Without that crud the seals, well, no longer seal so a leak develops.

Holy Moly!

Just why do you think them shows stay in business? How many times have you seen them say ANYTHING bad about a product? How long do you think they would stay on the air if they actually told the viewer the truth?
Them guys are simply a sales division for products. They get their entire show from the guys that make the products. If they say "this is crap" a couple of times they will be looking for another job.

C'mon! Surely we are smart enough to think about just what it is that a spark plug DOES! It makes a spark...right? Now after the spark.. everything else is up to the fuel, timing, head passages...etc. The spark is just a spark! All any plug can do is make a spark.. if there is a spark.. everything else that can possibly happen is left up to others..NOT THE PLUG.

A new or different spark plug can only make a differnce if it replaces a plug that isn't working any longer... Trying to compare a new factory plug to any other new plug will show NO GAIN in any of the things you listed.. HP, fuel consumption or emissions.

All we have to do is use our noodles a bit. THINK a little and you will see that a good plug cannot be improved on.

that may me but that doesn't change the fact that the dyno run was done the the EPA's sensors and analysed by an independent lab..... the results were shown 3 or 4 months after the dyno run was done........ they never would have had to say anything bad about the product...... Normally I don't even like that show but they did do an unbiased test on the e3 plug......

The test compared the Chevy recommended (brand new) plug to the e3. It was a fair test, the e3 lived up to its claim.

are the e3's worth the price for 7 crank hp on a fuel injected V8? prolly not.

on another note........ when I switched my fleet from dino oil to synthetic I noticed 1/10 mile per gallon decrease in fuel consumption over 20,000 miles (7 weeks)....... and almost no vibration when I switched to RP......

Missed my point.. Which is that no matter what they claim or no matter who tested their plugs.... IT SIMPLY CANNOT HAPPEN... All any plug does is make a spark.. If the spark occurs it is OVER! No better thing can happen.
Now would it be possible to make the gap a slight bit smaller or larger in this or that plug to RIG the test? Sure.
What we must remember in plugs is they must make a spark. After the spark everything else takes it's course. That course would be the exact same for any spark.
You may know that the threads on spark plugs are located differently (accidently) by the machine that makes the plugs. It would be possible to RIG a test by finding the sweet location of the electrode in the engine to be tested. Then using the plugs with the WRONG electrode location for the negative result and then installing the plugs with the correct SWEET electrode location for the positive results.
One must also remember that the plug company would be willing to spend many thousands to rig such a test... And then deny it all the way to the bank.
You have just reminded me why I never watch them sales shows. Sorry for the rant. I just wish every guy that is thinking about a tune-up to KNOW in advance that he cannot do better than the factory plug. No matter what he sees on the Tv or on the fancy yellow box.

So you are trying to say that all spark plugs are the same?

 

[Big Jim M]

Nope! Nope! Nope!!

So you are trying to say that all spark plugs are the same?

I'm trying to say the engineers at the factory tested the engine at the testing grounds for hundreds of thousands of hours.. They found which plug type and temperature they needed and then perscribed that plug to their plug company. Then, again, the engine was tested for hundreds of thousands of hours.. with the new plug.
Then the engine was sold to millions of regular folks.. the plug did and does all that can be expected of a plug in THAT particular engine. Of course I am speaking of ALL engine manufactorers.
Now when one makes the decesion to deviate from THAT PLUG.. Nothing better can happen! The best that might be expected from aftermarket plugs is that they MAY do as good as the plug that came in the engine.
So all plugs aren't alike.. not at all. Changing plugs is at best a crapshoot!
Oh BTW My new Chevys came with HD plugs that the factory sez will last 200K.. I'm gonna give em the chance.

apparently the Dyno and the EPA disagree with you. Everybody on this site said put up or shut up about different plugs ...... we said put them on the dyno...... horse power tv and the plug manufacturer went to the EPA for the sensors, the EPA ran the test and then had it analyzed by an independent lab. It was an un-biased and propper test ...... the test result do not agree with you so now you are trying to create fault with the test ..... Sounds allot like a certain former Vice President that created the internet........

I can tell you from the video of them firing the 2 different plugs .... the e3 had a brighter and longer spark (time, not length) ........ which would lead to a more complete burn..... which lowered the emission by a whopping 4% with a 7 crank horse power gain and a 10% reduction in fuel consumption on the dyno...... make of it what you want but the test was fair and the plugs did what they said they would do..... are they worth the price tag ...... no..... because you could prolly get the same numbers by clocking the stock plugs...... which no engine comes from the factory with its plugs clocked.



BTW ...... real trucks don't use spark plugs .........

C'mon guy get real! Of course it was a rigged test. WHY you ask? BECAUSE the outcome is IMPOSSIBLE!

A brighter/longer spark doesn't matter one hoot! At the first part of any spark the fire is started and the rest of the length of the spark is in BURNT gasses! This longer part of the spark can getcha NOTHING!
Which in turn CANNOT contribute to a more complete burn.. The burn happens after the start of the fire.

And in case you havn't noticed the length of the spark is controlled by the COIL! The plug simply allows a place for the energy to go to ground.

As for a 10% reduction in fuel consumption.. That's a joke, right? If it did happen then there is even MORE reason to suspect a rigged test.

I feel it necessary to add here: If ANY small addition to an engine would result in a 2 or 3 MPG result.. ALL vehicles would come with that addition in a few short months.. So do you SILL stand by the fuel savings?

Then more H/P and even less emissions.. All for advertising a spark plug.. It should be on the front page of the NY times..if true!

All we have to do is to sit down and THINK about what it is a plug does..
