Royal Purple

[Supreme Cutlass]

Is this oil as good as I've read? I'd like to hear the story on this stuff

[MonteCarloChick]

never heard of it :|

[stockgp]

i think there was a bg thread about this earlier this year. maybe try doing a search.

 

i've never used the stuff, so i won't comment

[chadz34]

I've heard it's good but any synthetic blend is equally as good. I run Quaker State High RPM full synthetic blend in the Z34. IMO if it's more expensive than Quaker State, just get Quaker State instead.

Ive been told by a good source that the stuff will free up lifters, quiet down motors, get rid of that factory option piston slap . When I put the GP back on the road, its getting royal purple.

wonder who your sources are

 

never heard of it getting rid of the factory piston slap but i've experienced it freeing up stuck lifters, and quieting down motors on the first (500 miles) oil change off the dealer lot.

[gp90se]

yea your not my only souce, kid here with a shitbox 3100 car quited the thing down on startup on cold days.

 

plus its purple, +8 horse

I myself am a Amsoil fan, BUT the guys at the shop told me that the Royal Purple is PREMIUM stuff and that it'll quiet the engine, run it smooth and lube it better, longer. The amsoil does the same but just runs for more money usually. Run 10w40 if your going to use it, recommended for high mileage engines.

[cutty]

i have always wanted to try royal purple ever since i first heard about it. but the only places around me dont sell it. and i also heard its very expensive for a case of it like $70 or so i think.

[boulevard]

I paid $92 for a case of 10W40 AMSOIL and 2 filters! Royal Purple will run you the same, but dont forget to run a better filter for synthenic oils. They are different from regular oil filters.

[gp90se]

I wouldnt run 10w40 in a 60v6, it wont hurt it but your mpg will be better with a lighter oil, and with synthetics, any gasket thats weak will start leaking. I will be running 5w30 amsoil in my 3.4 when its road worthy with a standard delco filter, change the oil every 6k, filter at 3k and replacing the 1/2 quart with fresh oil

[THe_DeTAiL3R]

I'd only buy sythetic oil if I had a high performance engine, or something that was OHC. Even then, I'd just buy Mobil1 or something cheaper.

[pwmin]

i just use mobil 1 1030 and delco 52 filter. if my engine had low miles and actually had good power, i would use royal purple, but what i use is good enough for this car.

 

whatever you do, please dont use any of the pa oils (quaker state, pennzoil)

Anyone whos seen my oil analysis posts from last year knows im a preimum oil nut.

 

Royal purple is a high quality synthetic oil desgined for rough driving conditions, high resistance to acid build up and long life.

 

AMSOil Standard and Royal Purple are the same level (just the next step up above Mobil1) and qulaity oil and our competitors. Depenind on who you talk to youll hear one or the other is the best. Both can run for over 20k miles on a single oil change as long as you have a good clean engine and change your filters out every 5k miles.

 

Using either you will notice a smoother running and quieter engine, it will also run cleaner, cooler and improve fuel economy a bit. Also you dont have to change your oil every 3-5k like with standard dino oil.

 

I personally have been running AMSOil for over a year now and also ran a test with amsoil who claims thier oil will last for 25k miles. I ran for 20k miles changing the filter (using good K&N or AMSOil filters) and sending in samples of oil for lab analysis every 5000 miles.

 

At 20k I still had enough TBN and a low enough occurance of metals to go another 5k easy but I decided that was good enough for me and changed it out. I now run nothing but AMSOil and change it every 8-12k with a filter change at 5k.

 

I just recently switched to AMSOil Series 5000 (the next step above regular AMSOil) because I got a good deal on a case. I didnt notice much of a difference with Series 5000 compared to regualr amsoil but then again im not driving a 500hp monster daily driver either.

 

The higer end race oils tend to be a littler thinner than regular oils and remeber they are full synthetic with addative to neturalize acids and clean your engine so if youve been using dino oil for a long time a good race oil will make your engine leak like a siev.

 

I used royal purple as well and noticed the same qualities and performance, my one complanit is that it is purple. a very dark purple. its very diffuclt to visually gauge the condition of the oil when it is so dark which is key when your running so many extra miles on a single change. AMSOil is the same color of vegtable oil out of the bottle so you can really watch it as it ages.

yeah i switched from regular oil----> mobil 1 synthetic-------> royal purple------> amsoil

 

i did not really feel a difference but i hear the worst "real" synthetic oil is better then the best regular oil

 

i am starting to get an oil leak and wondering if i should stay with amsoil or go back to regular high mileage oil

[gp90se]

fix the oil leak, going back 2 dyno oil wont stop the gasket from leaking, any dirt that may have been holding the leak from comming thru has already been cleaned by the synthetic.

[Supreme Cutlass]

Should I avoid switching if my engine has alot of miles? (abt. 150xxx)

[THe_DeTAiL3R]

I would stick with regular dino oil. At mileage that high you do risk unplugging potential oil leaks. You have a 3100? They don't need as much of a performance oil as say a 3.4 DOHC. You are best to simply get a decent oil like GTX and use good filter such as AC Delco, change every 3000miles or 3mths. I drove the piss out of my 2.8 and don't drive my 3100 like an old man either, and I haven't had problems with leaks/burning from either of them.

 

I saw on HP TV on an 84? Mustang 5.0 they put Royal Purple oil, syn tranny fluid, and fluid in the rear end and gained something like 8hp. Of course, who knows how long it was since the old fluids were changed so IMO I don't believe they really "gained" quite that much from those products just cause of the fancy name.

yeah, just fix the leak, switching wont help, ive got a small leak on my crank pulley but its a pita to remove and I loose less than 1qt every 5,000 miles so I could care less, Ill fix it next time I pull the engine out of the car.

 

if your loosing 1 qt or less every 3k miles and your not mixing oil and collant then you should be ok for a while depending on where the leak is.

[Dannymik]

like everyone else stated, fix that leak before you think of switching over. IMO I wouldnt spend a ton of money and through in some Mobil1 for starters(if you fix the leaks).

[Supreme Cutlass]

So, if my engine doesn't really have any leaks, would it be safe to try?

 

I kinda thought some synthetic oil might help clear out some sludge and put some testicular fortitude back into the engine...

all that and start some possible leaks...dirt helps clog those old gaskets that are wearing and becoming brittle.

[Supreme Cutlass]

Well, HOW possible is that? is it for sure? or just a chance?

[gp90se]

theres no real way to find out what ya chances of leaking are. If you pull a valve cover and see if theres any sludge buildup, it will give you some idea, but you really wont know untill ya try. my 3.1 with 90k had the o-ring leaking slightly, went over to full synthetic and the gasket gave out. I was loosing a quart every 15 miles. Changed the gasket, didnt have any issues after.

[slick]

I usually just run Mobil 1 full synthetic. Seems to work pretty good. Only bad thing is, at every oil change(ranges from 3000-5000 miles, depending on time and money), my oil just seem soo damn dirty.
