    RoyalPurple Synthetic 5w20

    Hi all,

    After much gnashing of teeth and wringing of hands, I've decided in my next oil-change to go with RoyalPurple 5w20 Full Synthetic.

    I know....I know.... most everyone is using Mobil1 5w30. I can even get that stuff at Sam's for $22 a 6qt case. However, I am turning risk averse in regards to my warranty. So, after consulting my service manager, I'm sticking with 5w20 and given that my only options are Amsoil and Royal Purple.

    I'm interested whether anyone has opinions on RoyalPurple in a positive or negative sense. I dont really want to debate 5w30 vs 5w20. I'm aware of those issues.

    Any comments?

    Johnny,

    I'm the lone Royal Purple user. I use the 5W30, though. This was recommended by the Ford Master Tech that takes care of mine and I change every 4-5K miles due to mostly highway miles.

    No problems to report.

    This is the first place I have ever heard of Royal Purple....I thought maybe when it was mentioned it was a joke...but then I was looking through a magazine at a Dr's office and saw an add for it...

    Personally I have been using Mobil 1 for the last 15 years on all my cars.....works great.....88 Cougar XR7, Tbird, F150...

    What does Royal Purple offer over other engine oils? Weight arguments aside (I hear ya Johnny) what make this oil so significant?

    For that matter, why does Mobil 1 seem to have so many loyal followers?

    I would love to know the difference, if it was explained to me, I may become a fan too.

    Until then, IMHO, the best oil is clean oil, and the recommended synth/blend seems more than adequate when short term and frequent change is also recommended.

    If the performance of the engine oils mentioned is equal, then...

    Anyone?

    Tetsu I too have listened to all the 5 30 guys and have developed this opinion based on many calls to ford and mercury. You should deffinately go with the 5 20 or 0 20. The tolerances in these new engines are light years ahead of the older ones. Also the engines are designed i.e. oil pumps and such for this oil. I am also reminded of back in the 80s when Ford first went 5 30 and all the experts like service managers and mechanics would reccomend at least 10 40. I feel this backlash is due to a resistance to change. Oils viscosity has little to due with its lubrication qualitys. The heavier oils were meant not only to lube but also to bridge gaps that are not existant in the newer cnc milled motors. Especially with aluminum blocks and overhead cams. I am sure some will mention race oils and to that point we dont run in the red zone for 500 miles at a time. Warranty issues be damned... The only thing I can get people to agree on is that full synthetics at this weigh will retain lube properties much better than dino rot. They also reccomend that we switch to synthetic trans fluid when we chage that...

    Well, at the risk of fumbling through this I think I'll give it a shot. I know of the "Purple" only because they were the main sponsor on Cristen Powell's Top Fuel dragster. The stuff has made it's way into many drag race motors with outstanding results for resisting "sludging", "sulferic breakdown","scuffing", "heat degradation" and whole list of others. I can't say for sure if she used the stuff in the fuel motor or not but I understand it has the formulation to handle this kind of punishment. There is no more extream duty then this and anything that can stand up to it has got to be good. The only reason this or any oil does not make into wide spread use among the pro ranks of dragracers is common "Oil Deal" a weekend of funny car racing will go through a 150 to 200 quarts of oil and thats works out to a lot of money. There are only two or three vendors handing out free oil to the teams and an outsider will find it tough to break into that game.
    The "Purple" in this royal concoction is not part of the "magic" potion" but rather part of the magic of marketing.

    Right ON with the Royal Purple...more merchandising than go..........something different, that's all, same oil as MotorCraft, as SAE has to make them all fit within paticular catagories......

    Just got 9K on my MM that I got last Aug, and it's just really getting broke in, or rather I am getting used to it. The nose of the car will fake you out if you don't watch it,threr's another 3 feet of car out there, and without a center stripe of some kind on the hood, it's e-z enought smack a curve. I have new wheels now, and they are goon stay new, without those dongs that happened the 1st time around.

    RoyalPurple is FULL synthetic. The better Motorcraft is only a blend. I'm most interested simply due to it's full synthetic nature and reputation for resisting to forming lacquers and sludges.

    PLUS, it's the only full synthetic besides AMSOIL which comes in 5w20.

    Who makes RoyalPurple? Never heard of it before this thread. Have driven two cars over 250,000 miles and a 4 cly. POS Pontiac sundird over 230,000 miles with no major repairs. Oil and filter every 3,000 miles. I have just started to use synthetic oil, although I'll use the Motorcraft 5 W 20 on the Marauder. John

    Tetsu,
    I work in an oil refinery and we have switched to Royal Purple lubricants for all our Rotating Equipment. This was a major economic decision as it is much more expensive than conventional oil (we used to use Amoco lubricants).
