Anyone have any experience with this ? I've looked into it a little, and their claims of increased HP/Torque are all pretty much the same as the rest of the synth producers (except for the Amzoil pushers, can't stand em). And it runs about the same price, around $5 a quart. I've ALWAYS used a quality brand conventional oil every 3K w/a new quality filter. But am interested if anyone has used this particular brand ? I just could not be brave (or foolhardy) enough to go extended miles just because some ad hype says less frequent oil changes are OK. But I don't mind paying a little extra for a better quality product, if indeed it is. Is it ? Thanks, Ken

 

Well I'll be brave and get this started. As you are going to find out here, everybody has a different opinion on synthetics.From all the research I have done, there are 3 reasons only to ever use a synthetic. First, extended oil changes. Second, the vehicle is subject to high heat such as pulling a trailer. Third, lots of short trips where it may not reach full operating temperature for any lenght of time. Otherwise, it is a waste of money.

 

I agree with last sentence of the post above.

 

[updated:LAST EDITED ON 09-Apr-02 AT 02:21 AM (EST)]To the original poster, Royal Purple is one of the best oils available. I wouldn't be afraid to use it.

Regarding synthetic oils in general; I'm suprised at the amount of hostility being directed at synthetic oil and the people who recommend them. I have no doubt that mineral oil works adequately and will protect an engine if you change it regularly, but what's with the slamming of synthetic oil? It works, too.

Edit: To the original poster; I use Mobil 1. WalMart sells 5 quart jugs for less than $18. My local WalMart has been selling it for less than $15 ($3/quart).

 

I went to Royal Purple's website and from what I read their oil is a syn-blend, it ain't pure syn. The only oil they sell that is pure syn is their racing oil. I don't think paying $5.00 a quart for a blend is all that great.

 

I would think Royal Purple is as good as any other synthetic on the market. But I beg the question, why? Putting synthetic in any truck seems silly to me. I can see a high performance engine using synth but I still think it is unneccasary. The only time I think that a synth can do anything a dino oil can't do is in racing situations and that is still debatable. I can not speak for all but Winston Cup cars but they do not even use synth unless a sponsor is involved. Richard Childress Racing pours in the same 76 oil you and I can buy at the store. Jeff Gordons car has Quaker State poured in every week. I will also bet that someone will chime in and tell me that the oil the racers use isn't the same as we buy at the store. Don't waste your time. Modern oils are so good that for synth to be considered superior (i.e. justification of the expense) they are designed to protect in your engine in ways it will never need. I'm sorry for ranting and getting off subject but if Winston Cup racers aren't using it what makes you think you need it?

 

I wouldn't do something just because I see racers do it. Racers use engines with dry sump systems with capacities of 8 or 10 quarts or something. They have oil coolers, windage trays, etc. You can bet they change the oil every time they go out. Racers tear their engines down all the time. Even with all that, many racers use synthetic oil.

Because of the chemistry of mineral oil based oil, it is naturally more detergent that synthetic oil. Dino oil is 'fuzzier', the carbon chains are a mixture of single and double bonds, where the synthetic oil are strictly double bonds. The single bonds make dino oil weaker, but more naturally detergent. So they can save a few bucks because they go through so much oil, and they can use an oil with less detergent additives.

Yes, 10 quarts of dino oil will last for 500 non-stop miles. But will 5 quarts of dino oil last for 5000 miles of stop-and-go 2 mile trips?

I consider my time to be worth something, so the slightly more expensive Mobil 1 synthetic oil is a small extra cost. I buy 5 quart jugs of Mobil 1 at WalMart for $14.50 or less. That's less than $3.00 a quart. For a grand total of about $25.00 I can give my cars a gold-plated oil change. That's a bargain.

 

I will just have to disagree. To think that anything we subject our vehicles to compares to the abuse and stress a racing engine goes through for 600 miles (Coca Cola 600) is silly. Those cars are over 8000 RPM for 600 miles. I'm sure some racers use it but if it was so great they would ALL use it and they don't!

Also to think that a Winston Cup team even considers saving money on oil is bizare. They are provided oil free of charge through sponsorship. Even if it wasn't the amount spent on oil would be nothing to a race team. In Winston Cup price means NOTHING!

 

We need to remember that race teams pretty much rebuild their motors for every race. And there are oils used that we have never even heard of. A few years ago will at a drag race I overheard a mechanic of a top Pro-Stock car telling a guy that they are using 0-30W !! I've see that weight around finally but you can bet if Quaker State sponsors a Pro-Stock car, they are going to get the premium 'skunk-works' type stuff.
I run alot of miles in stop and go traffic, and many short trips. I also tow a big travel trailer with lots of add-ons (bike racks, cargo carriers, 10 people inside, etc). I need my motor to go 200,000 miles, so what's an extra $20 4 times a year compared to the $32K I spent on the van ? And I don't know if you've noticed, but cars get MORE expensive every year. I expect my next rig to cost $38K for the exact same thing.

 

Royal Purple is the best old on the market. I use it in two out of three cars(my mom's and mine). It will give you more hp/torque. As a good example as how good this oil is; Royal Purple recomends that you do NOT use this oil until your car has at least ~10k(i think, it might be less) miles, other wise the piston rings will not seat properly. this is why it is only in two out of three cars. when i first put this oil in my car i saw a ~100 - 200 rpm increase at idle and that was at 50k miles. I recomend this oil to everyone.

If your idle rpm went upits not due to your oil. Idle speed is controlled by the computer and if its not what it is supposed to be something else is wrong.

 

it only did that until it releared its idle position.
