Anyone who's actually took the time to do an independent oil analysis which I have on Mobil 1 and Royal Purple there is a reason why Royal Purple costs more. Royal Purple has a much more robust additive package in comparison to mobile 1 which is mainly what you're paying for. Royal Purple has an SUS viscosity of 7.0 with a TBN value over 6. Royal Purple HPS has over 1, 300 parts-per-million zinc and phosphorus with around 12 to 1300 parts per million calcium with around 300 parts per million boron with about 1100 parts-per-million Molly and other detergent based additives. Mobile one barely has half of the additive package that Royal Purple has and this video is incorrect anyone who only changes their oil yearly you're going to ruin your engine it doesn't matter the quality of your motor oil all oils breakdown over time due to moisture and fuel dilution as well as additive package depletion there is no oil on the market that can remain stable after one year of use. Even with a very high-quality synthetic oil that falls into a group 5 base stock I would not even recommend taking over 8000 Miles. And for comparison Mobil 1 oil base stock only falls under a group 3 refined mineral oil it's not even a true synthetic.

I've been running Mobil 1 high mileage in my Colorado 2004. 512 thousand Miles and still purrs like a kitten. World class motor oil.

I did my first Royal Purple oil change today. I used to run Mobil 1. Suffice to say, Mobil 1 can kick the curb. Right off the bat there was a HUGE difference. Engine ran MUCH smoother, oil pressure was way better, and the engine was much quieter after the change than Mobil 1 ever made it. I used the HPS Royal Purple. It may be expensive, but is well worth the price guys.

I used royal purple in my 2011 honda civic and it just hit over 500 000 kms on it and still running same moter nothing has been changed in it i say its worth the extra bucks

Just switched from Mobil 1 to RP for my 08 Mustang GT. RP filters use completely synthetic media vs Mobil1 semi-syn with cellulose.

2017 jeep compass with 130k miles using royal purple the entire time, we haven't had any issues whatsoever just basic maintenance like brakes and filter changes, runs like a champ and we change every 5k miles and we don't burn oil and it comes out pretty damn clear

Mobil 1 extended performance I use it on my 2012 Ford Focus makes it wrong perfect smooth Mobil 1 extended performance best oil ever

I’ve used both and I’m a fan of both, but there’s a reason why Royal Purple costs more. For the average everyday driver who just wants a good synthetic oil, Mobil One will do just fine

[Endoe.McKronic]

I used royal purple in my 2006 civic. Before oils, they would burn oil on long trips. With the purple, the car was running great. No problems, but I still had to put in a few drops if I took a longer trip. Anytime I checked the oil, it was semi clear. Never BLACK like the others.

Someone knows if royal purple oil can be used in a Toyota tundra 4.6 v8 ?

I’ve been using mobile one in my 2016 Chevy equinox for several years now and I have to replace it every six months which is when the car tells me to replace it

Thank you for this video. My 2004 Honda Pilot had 225, 600 miles on it for the Blackstone Oil Report: I bought it brand new. Most of my driving is 30-100 miles start to stop. I have used RP 5W30 EXCLUSIVELY for the entire life. I change the RP oil every 7500 to 9600 miles and use Mobile 1 Extended performance oil filters. At 200, 000 miles I upgraded to RP 5W30 HMX. Here are the comments from my latest Blackstone Labs oil report.: "ERIC: With 225, 600 miles behind it, the 3.5L V-6 in this Pilot is still going strong. This oil was run longer
than the ~6, 600 miles our universal averages for this engine type are based on, yet wear metals are close
to or lower than averages. Usually, iron will increase as the oil is run longer, and this 7-ppm reading after
9, 600 miles shows low wear at steel parts. That's really nice! The TBN isn't so good, though—at 1.5, it
shows the oil was running low on active additive. With that, we wouldn't suggest running the next oil much
longer even though all of the other results are great." PS: My 2004 Pilot never leaks or burns any oil at all. Fuel milage and power are the same as when it was new. I now have 231, 000 miles on it. RP works and I am happy. Would I be happier if I had used Mobil 1 oil: perhaps?

Can I use royal purple on a cammed 5.3?

[Rpeices]

Did this video say replace yearly ? I have used both and i still replace it every 5 to 7000km

[Randze]

Just recently did an oil change on my 2015 535i used the Mobil1 extended performance but I think im going to do royal purple next to see how it is

[rayterrell]

I have used Royal Purple for over 30 years in all my vehicles and with oil changes every 5k miles. I never experienced oil consumption or rear main seal leaks. I keep all of my cars at least 10 years and over 100k miles usually. I just sold my 2002 Tacoma with 300k miles and it ran like the day I bought it and only because I wanted a Tundra. My new Tundra has a V-6 with twin turbos. I plan on using RP in it and my new Lexus LC500 (Japanese Corvette) as well. 😊

After replacing the lifters, bearings and rockers on my 3.6 in my 2015 Grand Caravan, the mechanic told me to only use this oil to avoid this recurring repair for which this engine is notorious for. I change my oil every 3 k miles.

[stlwolf]

Literally every one of these comments have no data links to back anything. Royal purple is not the same as it was when it came out either. Formulas were changed and costs cut. I used to swear by it, but they have multiple versions of their oils and they vary drastically, so pay attention to what you're actually comparing. Compare both companies high quality synthetics against each other. Too much heresay!

Royal purple v.s. Quaker state full synthetic

This video did not do justice to Royal Purple. I have used this oil for 15 years. This oil is so good that sometimes i think it may be an overkill for daily use. First and foremost, If an engine has a ticking noise, and you add Royal purple to it, that noise tends to reduce. Royal purple cleans the internals of your engine so well, that some parts may still look like new when you open your engine after years of constant oil change. I use to change my Royal purple every 2, 000 - 3, 000 miles and I have never been disappointed by Royal Purple. I truly believe Royal Purple may have forced many of the other oil companies to start using group IV base oils instead of the group III base oil they once used to refer to as Synthetic oil. I think Mobil 1 used to be a group III oil but I think they may have switched to group IV oil simply because the modern day engine design, the manufacturers, and their customers simply demand the best. I believe Mobil 1 may be on the same level today as Royal Purple. So, the modern Mobil 1 formulation is now an excellent oil and i would recommend it. But, Royal Purple will remain my love because it was Royal Purple that showed me how strong a synthetic engine oil should be. I drove an engine 200, 000 miles very hard with Royal Purple and the engine was still kicking hard---no issues. Royal Purple actually helps your engine squeeze out the most horsepower possible in your engine for the current tune. The only non-synthetic oil I trust just as Royal Purple is Castrol GTX---exceptional non-synthetic oil---designed for hard driving.
