Is anyone using any of the Royal Purple products? I have heard and read good things about them. I am currently using the differential and transmision fluid in my bmw. Let me know what you guys think.

Royal Purple Website

 

I've also been looking at Royal Purple, unfortunately I haven't been able to find anyone with any more information than the website

 

i've used royal purple (engine oil) in my car after switching over from redline synthetics. i just found it cheaper, that's all. i didn't notice any difference ibetween the two performance-wise. my car ('88 5.0 lx) had over 150,000 miles on it when i got it and the oil pressure would gradually drop over time, however when i switched to "true" synthetics (redline / royal purple) the oil pressure would stay constant between oil change intervals. these products also have a different feel and smell to them - i did my own oil changes. i for one, would recommend using royal purple. you'll even pick up a few horsepower. of course, it all depends on your personal preference. i for one, am a believer in synthetics. i say go for it once you've put some miles on your car. btw, royal purple really IS purple... and no, redline is NOT red. just thought i'd add my .02 cents

 

I use Amsoil - i believe that's as good.

 

as i have been told from a royal purple rep...yes there oil is good anfter the engine and components have broken in..using it too early and the parts will not break in properly....

 

I've heard this in the past but never used synthetics. Considering it with my new Mustang. What I'm wondering is what is to early? How many miles should I go before changing? Suggestions appreciated.

 

maybe 6-to-8k......

 

I'm changing the oil too often to go to synthetics.

 

Other than cost and availablity I haven't seen much difference in the true synthetics. They're all good
Our 1st change was at 500 with Dino oil.
2nd at 1,000; again with dino.
3rd was ay 5000 and shifted to Mobile 1.
Maintenance schedule is to now change at 6-9K
Same as on my last several drivers; one of those we put over 500,000. What has worked for me for years.

 

You can extend the intervals, if you change your oil every 3k, just change the filter and top the oil off after the next 3k and change it at 6k.

From what I understand you can go as much as 10 to 11k on a good synthetic provided your vehicle is not exposed to harsh operating conditions (I think only a vehicle mostly driven on the highway and at a good amount of time at operating temperature really qualifies). with a change in filter every 3k and top off the oil unitl you hit 10 or 11k and time to change.

 

went to mobil 1 synthetic yesterday at 2,145 miles with mobil 1 top O line oil filter----guys at the oil shop were great----$69 normally $80 with that oil filter---i will change every 5-7K----

 

80 dollars for a oil change ..that seems steep...

 

i look at it this way---every 5-7K---instead of every 2-3 K with normal oil---i would just do it myself however---i live in a condo complex that is not too conducive to it and there is very little clearance to do so without putting the car up on stands---plus, come end of october its a tad chilly out---

 

I am still on my first synthetic change.Only have 2,500 miles.Most of them have been down the 1320

 

My wife probably averages 50 miles a day, currently 20,000 miles. Depending on how much I'm at the track, I usually will change it 2-3000. I've changed the tranny fluid 3 times already.

 

Thanks for the info. I'll probably wait until 6k and go to Royal Purple.

I changed to Synthetic (Mobil 1) after 500 miles. I have Royal Purple in the trans. I still change oil every 3000. I do it myself and it costs under 40.00 bucks. I drive in extreme heat. Its worth the extra cost to me.

 

I've ran Mobil 1 synthetic since 5k miles. I also do it myself every 3k miles.

 

I'm just a mechanic from the Harley world, so this is somewhat apples to oranges. However you guys changing synthetics every 3k miles might want to think again. It's been my experience guys who go to synthetics and don't go longer intervals between changes are the guys who have problems. People don't realize oil doesn't just lubricate it also carries out the "trash" of the motor. And it doesn't absorb the "trash" very well until it starts to break down. So what ever oil you're using make sure it's starting to look dirty before you change it. It's been my experience that good conventional oils can take up to 5000 miles in good conditions to begin to break down. In fact that's Ford's own recommendation.
So far I have yet to be convinced of the whole sythetic movement. I'm not saying you should avoid synthetics either. IMO they are just an alternative and are best for fleet vehicles so the mechanics don't have to do as much regular maintenence. I also don't think the price is worth the benefit as I know guys with as many as 200k miles on an air cooled Harley and only use HD 20w50. Just food for thought.

 

Not wanting to start one of those oil battles but I will have to go the other way. I have owned and worked on Harleys and the others for the last 26 years. A good friend of mine owns the Harley shop in town where I live. I have used Synthetic religiously and changed at 2000 or less. I have never had or known anyone that has had a problem while using Synthetic that had to do with oiling. I have torn down motors that have used both for variuos reasons(usually to modfiy)and the synthetic motors are spotless inside. The dino oils have burnt additive diposits. This is the same with cars, bikes, boats, etc. If you are not using Synthetic that's your deal. You are not taking advantage of the best out there though. The advantages have been proven over and over again. I can promiss you if they had not been proven, manufactures would not be using them from the factory.
