I’ve done 2 regular oil changes since my new engine and now want to switch to synthetic. Does anyone have an opinion on which oil is better Mobil 1 or Royal Purple?
Thanks

Said there, and I'll say it here again, AMSOIL > *

I'll say Royal Purple, I'm using it for over a year. No problems with it so far.

Thanks but, why Amsoil over the other two?

A couple of my friends use it on their car non-maximas w/ the tranny royal purple fluid and love it for some reason. They say the car feels more responsive. What do you think?

You can use Safeway brand motor oil and you won't have problems. How does NOT having problems supposed to validate this oil? You AREN'T SUPPOSED to have any problems.

With regular filter changes, you can run AMSOIL oil for about 10,000 miles without needing to change the oil It's engine life is unmatched from what I have seen thus far. But to be honest with you, after sveral thousand miles with AMSOIL, I will never be switching.

Amsoil=too many additives, not enough oil, and too strange for me, if its so good let pepboys sell it, i feel similarly about Mobil 1 EP

RP=GroupIII not a true synthetic, not worth its cost.

Mobil 1-your best bet unless you happen to have a stash of Green GC in your possession, which im sure you dont, so id say go M1.

This is from somone who knows oil pretty well, and VOA's and UOA's too. all are fine choices and id rank them
1 M1
2 Amsoil
3 RP


good luck

what would you rank green GC amongst those 3 that you listed?

I got 15qts of green just chillen waiting to be put in later this spring!

Why don't you try both and see which one you like better? Pepboys sells both in 5W-30 so it should be easy for you to get. I'd probably tell you Royal Purple because I like the way it feels and performs over Mobil1 and I'd like to be the outkast here.

I just switched to Esso XD3, 0w30, PAO, full synthetic on the weekend and the Maxima is purring like a kitten. Come on up to Canada and buy some real oil!

Thanks for you opinions, but I will probably stick with M1.

I have been using Mobil 1 and I guess I am happy with it. Its somewhat difficult to tell what is actually better. I recently read a test done on a few motor oils and usually the higher the moly rating the better. From the test results:

Redline > Royal Purple > Mobil 1 > Amsoil

I would say Mobil 1 is still a greay syn oil but if you are highly modified or beat the **** out of your car then you can go for the more expensive Redline or Royal Purple.

shurik, do you buy your Royal Purple locally?

No offense, but your analogy doesn't really hold up. Amsoil isn't sold at Pep Boys because of their chosen business model. That has no bearing on it's quality. Amsoils additive packages is 2nd to none. Mobil 1 EP also has a beefy additive package which is required for extended drain intervals. I think the quality has been shown since it's inception when it was the first synthetic oil for passenger cars. Time and time again both Mobil 1 and Amsoil have shown to be superior oils, especially for those doing extended drain intervals which I have done since 1994. Royal Purple has shown time and again that it's use shouldn't be for passenger cars unless you prefer to waste your money on an inferior product and you prefer to change your oil every 3000 miles or less. Redline has also shown to be a very good oil as has the German Castrol.

Royal Purple's oil analysis has shown to be pretty bad in comparison to most of the other syns. It breaks down way too quickly and if you are hard on it, you'll be lucky to get 3k out of it. Royal Purple is great on the race circuit as the oil in race cars are changed after each race. RP's additive package is extremely weak for daily use. Not to mention it's the most expensive "boutique" oil.

Stuck with M1.

Im going to stay with Mobil 1 also. Virus, do you have a link or anything to the comparison that showed Royal Purple breaks down fast?

joew

synthetic oil in general is better than dino oil. most synthetic oils are fine you just need stick with the oil change interval. Lots of people on this forum change on every 6k.

As you know, motor oils are comprised of base stocks and additives. Both of these broad components come in various qualities and are used in different combinations to achieve the desired quality, performance and price of the final product. Even the best PAO basestocks, like those used in most AMSOIL motor oils, require additives to enable the final product to achieve the desired performance outcome...base stocks without additives won't work. All factors considered, taken as a whole, AMSOIL products offer outstanding performance and they are a good value.

Concerning the marketing strategy, AMSOIL was introduced in 1972 when most people couldn't comprehend the concept of a synthetic oil capable of extended drains. AMSOIL was (and still is) a relatively small, privately owned corporation. Back in '72 the company's production capacity and distribution capabilities were limited, and how many retailers do you think would have purchased the product to put on their shelves??? So AMSOIL made the decision to sell the product thru independent dealers...throughout the years the company has maintained that marketing approach and they have remained loyal to the independent dealers who have made the company the business success story it is...the company has grown at a substantial pace, and they are continuing to do so with innovative and high-quality products.

I think we would all recognize Snap-On tools as about the best there is in the tool industry...when is the last time you saw Snap-On tools at Pep-boys or other retailers? You won't as they are sold by independent dealers just like AMSOIL is.

Here are two UOAs from BITOG wih long OCIs from a 3 Series. The M1 had 2K miles more than the RP, but it still had buffers left (though it had 5 qts of make up vs. 2 for the RP). The RP's TBN were gone.

Just dropped the GC in my '99. Replaced the M1 5w30.

The M1 is a very good oil but the VQ30 definitely prefers a heavier 30 weight. My Max is quieter and runs slightly smoother.

Love the GC.

steven88

iTrader: (28)

I know VQs are known to like heavier 30wt oils....GC would be the preferred choice on this one (or any other heavy 30wt oils)

Some engines like the thin 30wt oil...GC would make this engine feel sluggish and perform ....try sticking with M1 on applications like these...since M1 is a thin 30wt

Hey Steve what do you use, M1?

I'm currently running Torco SR-1 5w-30....I got 12 liters for free! Not many people use this oil but I don't have any problems with it...

I'm planning to switch over to German Castrol once my oil change comes up...I already have 15qts of green just sitting around
