## Questions & Answers

**Q: Is this oil vw 502 rated**
A: I don’t know what your asking and I’m not gonna gts it, but, this is the best oil you will ever use.  I use it in my 95 Bronco, 17 Explorer Platinum, and my 18 King Ranch.  The bronco has 182K on it and uses almost a quart between 5K oil changes.  Bottom end will be slick when I ever have to take it out.  I run all royal purple fluids in trans and rears.  I believe in this oil as much as I believe in Jesus!

**Q: whats has a better VI this or the 10w30? Or  better numbers? htsc?**
A: Which VI test, Kinematic or Dynamic? So it’s not easy to give an easy answer. If you have an older car with lots of miles, then 10w30 can be the better choice over 5w30 in a Dynamic VI test; however, if your car isn’t really old then 5w30 is always the better choice. You can’t compare the VI because the 10w30 will always be lower, as the range between winter and operating temperature is less. I think Group is more important to you so you really should be looking for Group V oils, like Motul. They use ester, but the price obviously goes up, eh.

**Q: if anybody has used this on a 1992 firebird how is it?**
A: You should always mention your engine in your vehicle as well as the environment and type of use the vehicle gets when asking questions.  What specifics are you seeking when you ask "How is it?".
It is really not a reasonable question and I think you would greatly benefit by participating in some motor oils discussions and learn about motor oils.  Bobs The Oil Guy is the most popular I know of.
It is typically overpriced in my opinion.  The closes thing I have to your vehicle is a 1998 Trans Am WS6 with 5.7L LS1 engine with various modifications and dyno tune.  I don't use the current formulations of RP.  I have had reason to mostly tear my engine down and it shows no signs of premature wear on anything which is really how you will truly know how it is doing.  I spent over 4 years studying motor oils and filters and I use different ones in both my 4 wheeled vehicles and superbikes.  Superbikes get group V Ester basestock oils from French and German manufacturers.  Street cars including the TA get group III synthetics and synthetic filter media oil filters.  I use the rebates that come out every few months so it saves me a lot of money and I change my oil at less frequent mileage than recommended.  It would be fantastic if you were to learn as much as you needed to know about motor oils and filters and make your own informed decision.  And remember that formulations for all motor oils are constantly changing (and they don't mention it) and new products come out so what you might select today may not be what you select next year.

**Q: Is this Group IV oil?**
A: NO is the answer.  And there are only about 5% that are TRUE SYNTHETICS.  This is a group III "synthetic"  See Mobil vs Castrol and you will see why that law suit determined that in the US you can call oils that use CONVENTIONAL base stocks, Dino oil however you want to say it that has been highly refined through processed such as hydrocracking but would NOT be legal to sell with a label calling in synthetic in many places such as European countries like Germany.  Royal Purple USED to be considered a P.A.O. oil but changed without notice to customers (like any oil company would) but of course did not alter the price.  Remember there are also Group IV oils which are Ester based which is what I use in my motorcycles.  Though todays group III oils can be some of the best choices for your average passenger vehicle.  They are also cheaper with brands like Mobil 1 and Pennoil Platinum Ultra running rebates of at least $12 or more every few months.  With the cost of a 5 quart jug on sale on Amazon or any day at "Wal ly World" going for $24 you end up paying $12 for 5 quarts which means you can save money and if you are on the fence change it more often.  Remember an oil filter removes particulate matter from the oil NOT byproducts of the combustion process including things like acids.  So you do want to change both the oil and filter.  Use your manufacturers owners manual as your first maintenance schedule to follow and go from there.  Oil itself does not "wear out' but the additives do deplete including things like viscosity modifiers and detergents and contain those build ups of contaminants so changing your oil and filter is important and is vehicle and use specific.  Anyone that gives advice to others on what viscosity to use or what oil change intervals are appropriate without even knowing what the vehicle and use are should be ignored and shunned.

### ⭐⭐⭐⭐⭐ It's Not Just Hype
*by T***I on April 29, 2024*

Listen, I get it. Everyone has some automotive elixir or magic potion they swear by. "Put this in your tank, and it will be like a new car!" We all wish it were true, but in reality, there's nothing you're going to put in an engine to bring it back to life, or keep it running 500,000 miles. But I can tell you this with complete honesty: Royal Purple was (and continues to be) absolutely worth the money in my case. At around 140,000 miles, the engine of my 2008 Jeep Grand Cherokee was noticeably louder than it was in its youth. Not a terrible noise, but there was definitely a mechanical clatter that wasn't there before. I'd also started to notice that when I changed the oil, I was getting less and less back out. I'd put 5 Qts in, and 3,000 miles later I'd drain out just 3 or even 2.5 Qts. I never noticed any oil on the driveway, so I don't know if it was burning it or only leaking while running, but it was going somewhere. One morning, after I'd gotten a little lazy and went a bit past my usual 3K oil change interval, I noticed the oil pressure light starting to flicker. Checked the stick and it was just barely registering. Something had to give. I didn't want to be the guy putting a Qt of oil in his old clunker every week (in other words, my Dad). So I started looking around and saw that Royal Purple was making some big claims with their high-mileage oil. Rejuvenating seals and cleaning your engine, that sort of thing. I kept doing more research, and the surprising thing was that more and more people seemed to be backing it up. What finally convinced me to make the switch was a YouTube video where they took the valve covers off an old engine before and after running Royal Purple through it -- there was no denying it looked cleaner inside. So I spent the money, even got the proper filter. Went ahead and did the shorter interval for the first change that they recommend to get the loose stuff out of the system before really settling in to the fully synthetic oil, even though it meant spending double. I figured if it worked, it was worth the money. Well, that was over 20,000 miles ago, and I'll be damned if things haven't improved. The engine is without question quieter, and at idle, is noticeably smoother running. But the best part is that the oil loss has been reduced dramatically. Now when I put in 5 Qts, I get 4 Qts back out. It's not perfect, but considering nothing has changed other than the oil, I think that's a big win. I no longer have to religiously check the dip stick every week for fear of an empty pan before the kid needs to go to school. End of the day, I'm just one guy who enjoys fiddling under the hood from time to time. I'm no expert, I can't tell you how or why things improved with Royal Purple. Maybe it's all just coincidence? All I know is that it's worth it for me to keep spending the extra money. I want to keep my engine running as well as possible, for as long as possible, and to me that means always using Royal Purple.
