AMSOIL vs MOBIL1 vs PENNZOIL vs ROYALPURPLE VS MOTOCRAFT (5W-20)

[racinreddy]

Hi guys,

I have been seeing lot of marketing strategies used by different oil companies to claim that their oil is superior to others.:shrug: I am looking for full synthetic oil 5w-20 for my v6 stang as its nearing its oil change interval.

Please drop in your recommendations /thoughts what according to you is the
1) Best FULL SYNTHETIC OIL
2) Best oil filter.

Also I have setup a poll so please vote for the best one out in the market so that it will also be useful to others for future reference.

AMSOIL SS and AMSOIL EO filter... The argument against it is that it's "expensive", but I'm not sure who can bitch about an extra $40 or whatever per oil change after they bought a $20K-40K+ car...

Daltron beat me to my reasoning.. I've ran amsoil once and mobile one every other time.. I got a steep discount on the amsoil and I think it's great oil! Do I think it's any better than mobil one? Not really. For the cost difference and since I swap oil every 5k anyway there's no real advantage for amsoil for me.. That said, other fluids I wouldn't hesitate to spend the extra coin on as they'll sit in there longer.

Most of the comparos I've watched and read stack these two really close with the main difference being price and availability.

Also, it's a V6.. It's made to take a beating and still run fine. They engineer those motors to last forever with minimal oil changes. Keeping up on scheduled maintenance will make it run better than most on the road

Amsoil is the best. And you spelled Mobil 1 wrong in the poll.

I think royal purple is the best stuff out there even better than mobil 1. I read that in some particular races, royal purple is the only thing that keeps the engine together ( i read this info on some tractor high performance race forums).

They stated that royal purple IS the only oil that can perform under the extreme modding they do to the engines and imagine what it can do for our daily drivers I guess.

I use Amsoil when I do it myself. When it's cold out and I'm lazy, I have the dealership do it with motorcraft synthetic. I have also used Mobil 1. TBH when it comes to the top oil brands I feel it is more of a Coke vs. Pepsi argument, you can't go wrong with most of them.

AMSOIL FTW.

Yep any full synthetic oil will be fine.

"full" synthetic oil is better described either as a Group 3 or Group 4 engine oil. For instance, Mobil 1 is a "brand" which sells both Group 3 and Group 4. I use 0W40 Mobil 1 which is a Group 4.

Don't believe any 5W20 oils are Group 4, but rather Group 3 ("Severely Hydrocracked") blends.

Meh, I just use Mobile1.

When I first got the car, I was like "I'm going to put in the best oil and filters, etc I can". Saw the prices, especially for Royal Purple and AMSOIL and said nope!

I'm sure AMSOIL is a bit better than Mobile1, but how much does that actually matter?

I just put Mobil 1 a month ago and have been noticing my oil temps getting close to the yellow line at times. Checked the oil, and it looks fine, and oil pressure shows normal as well. I'm planning on changing the oil again to be on the save side. Might try Amsoil

Royal Purple handles the heat of Texas summers very well. Also I believe that a full spectrum premium oil such as Royal Purple is "cheap insurance" if you want to have your. Mustang log many trouble-free miles. My Cyclone motor really seems to run "smoother" since I switched over to Royal Purple.

interesting thread. I normally run mobil1 or valvoiline full syn in most my cars. might have to try royal purple.

Well that's something I would be watching out carefully as I have chosen Mobil 1 extended performance 5w-20 over remaining brands for recent oil change.

Engine feels little harsh not sure if it's just the sound from new borla stingers which are making me feel so.
