Thinking of swiching to royal purple - Toyota Nation Forum : Toyota Car and Truck Forums

I am thinking of swiching to 5-30 royal purple oil, does anyone recomend it for the 1MZ? What im worried about is the API, The oil cap on my engine says to use API SH and the royal puple bottle says SL, I saw it when i changed the oil on my dads truck with that oil but that was a 10-30W oil. Has anyone used it with great results? Anyone out there with bad results?

I've already searched but i din't really find anything use full.

Oh and i already took care of the oil leak i had from the valvecover gaskets by replacing them.

Thanks.

I used Royal Purple in my 1MZ a while back intending to go for a longer drain interval. At 4500 miles I had an oil analysis done and it showed very little lubricating additives left so I switched to AMSoil. Had an OA done on the AMSoil after about the same miles and had a much more normal reading. May have just been a quirk but I have not used Royal Purple since. Also learned it is not a true synthetic but a highly refined dino oil. Did seem to have a little extra oomph though as Royal Purple advertises. If you use it I would say to stay with normal 3,000 mile oil changes.

Id just use Mobil 1 if you want the best oil available. I dont know anyone who uses the purple and ive never heard anything about it, good or bad.

SL rated oil is fine for an engine calling for SH, because these are API grades in alphabetical order of quality of the additive package, with A being lowest quality, B higher, etc. So SL oil is better than what that engine calls for and it is ok to use a higher quality oil in it but not a lower one.

IMHO - Royal Purple is a waste of money. At another board I frequent, someone did a before and after dyno test with Royal Purple and absolutely no change in HP or Torque...so much for their claims of a 3% increase. Other than that, I've not hear any thing bad. But if they lie about this, what about their other claims?

I've used Castrol Syntec, Penzoil, Texaco, etc. in my Camry for 13 years and she still runs like the day I bought it.

It won't hurt the car. I have friends that use it. Some like it, some don't. Most of them say the only thing your gonna hurt is your wallet. Stick to what you are using now. If your doing your oil changes at 3000 miles anyting that is recommended for your car is fine.

Nevermind, gues im going with mobil 1 super syn intead of the purple.
But before i swich to synthetic i think i might put in their synthetic blend of clean 7500 so it wont start burning oil like i've read on another thread.

Im am using clean 5000 but i don't think it has a very good amount of film strengh because i think that i have had a very slight rod knock since i swiched to it.

I'll let you guys know how it turns out after i change it today afternoon or tomorrow.
Thanks.

i been using Castrol Syntec for the past two oil changes it seems that my engine feels smoother than when i was using Mobil 1 but def recommend both

I bought the clean 7500, finished changing it on sunday night along with a drain and fill of atf and it has been great so far.

I used Royal Purple 5W-30 in my '94 V6 and it burned it off really fast and my car never had burnt oil before. It did feel a bit more powerful, but it didn't seem like the Camry liked it much.

Yea, im noticing that it's just a waste of money, My dads truck has it and it lost it's color very qiuckly. I think i will never buy that oil again.

I've used RP 5w20 in my camry. It gives decent used oil analysis report. The RP 5w30 suffers from oil thinning and will eventually thin out to a 20wt, but our toyotas can use 20wt, so its not really a problem. RP 10w30 would have less VI (viscosity improvers) so it would be more resistent to thinning. From what I know RP street oils are 100% group IV PAO base, only the carrier oil is group I or group II. It's good oil and gives good UOAs, but dont go beyond 6k miles with this oil.
