Oil You use & why/Pros & Cons

svtsilversnake · Mar 23, 2008

I saw the Oil vs. Oil thread and decided to make a poll. Explain what you like about the brand you use. If possible post actual facts and pics of motors that have been torn down after using 1 brand only its whole life or close to. This is somthing I have always woundered because i know RP use a friction modifier to improve bearing race surface,and to polish internal parts.(to me that sounds bad but I still use RP)

I chose royal purple because of all the information I found on it that pointed to its supiriority. Of course, depending on whats disclosed in this thread I may feel otherwise. All I care about is the quality of what I use. So let lets start. :thumbsup:

I guesse I should have put this in road side. MODS!!! Would you please move this to road side.

I would use Amsoil if I could get it at WalMart but I can't so I use Mobil1.

T-Pain808 · Mar 23, 2008

Thats the only problem amsoil ain't the easiest to get, But I have a dealer pretty close to my house. Brings it in with no shipping. I think the most important thing (besides using synthetics) is what oil filter and air filter, and thats why I went with Amsoil, I think they have the best and they can back it up. That nanofiber stuff looks like its the real deal.

Amsoil OW-30 here for 60K miles now. It's proven to be better than all the other major brands. I use their oil filter and air filter with my Steeda CAI.

I use Royal Purple 10w30 street oil on track and on the street.
I have been using it since 2500 miles. I have no tear down pictures because there is no reason to tear down. I recently added the Canton road race pan and windage tray, and there was no evidence of anything starting to go wrong.

Royal Purple gets bashed by people who I suspect don't really know WTF they are talking about.

I have 20K HARD MILES on this thing and have no intention of letting up now.
There are plenty of high quality full synth oils available that do an excellent job.
I choose to run RP and it is working for me. I run it in the engine(stock oil cooler), the trans(no cooler), and the diff(also no cooler).
If anyone knows a tougher application to test oil on than what I do with my car, feel free to bash away with your humorous lawn mower comments etc. while you explain how much more stress your application has and why it proves your choice is "the best".

Royal Purple may not be the best,( I'm not really qualified to say what is the BEST) but it IS WHAT I RUN, and it is WORKING! :rockon: :beer:

+1 pretty much the reason I run Mobile1, good oil and readily available.

About2bite · Mar 24, 2008

I use Valvoline Fully Synth

What oil weight do you guys go with?

What weight oil does Ford recommend for the GT500's?

I use Mobil 1 as well, but do the oil change at 2800-3000 miles
I know I can wait, but can't bring myself to do so :nonono:

You may even be able to go longer than that, if you have an oil analysis done it will give you some good info on your oil and whether or not what you are running is the best for your motor. It's about $25 to have it done, i'll probably send mine off the next time I change mine since i'm trying a new oil weight and manufacture.

Where do you take it to have this done? It seems to me that the only way to truly tell If an oil has done a great job is to tear down after many hard miles:burnout:

hotcobra03 · Mar 24, 2008

i used castol gtx 5-20w 6qrts and i bottle of stp on every oil change..i have well over 200,000 miles on my 03 cobra and my oil is never changed on time..im doing the test of time,,its alot funner than an oil analysis

Amsoil 5w-20

Switched from Mobil 1. I figured for $.80 more per qt. I might as well get a true synthetic.

If Mobil 1 was priced with the rest of the semi-syn's I'd still be using it.

Did you see a change in oil pressure after going to 10w-30?

Mobil 1 is a true synthetic.

They use Group III oils and some people consider that to not be a true synthetic.

I think only Amsoil and RP use Group IV oils and are therefore considered by many to be the only "True synthetics"

Even though The National Advertising Department of the Better Business Bureau ruled that Group III base oils can be considered "synthetic" because modern oils made using hydroisomerization technology have most of the same performance features of the early synthetics.

So, yes, Mobil 1 IS full synth oil, unless you wanna nitpick.

No.

It does not get that cold here in the winter, so I don't bother with the 5W, a 10W gets it done ok.

On the hot side I figured I would be better off with the protection of a 30 weight compared to a 20 weight, since all the internal clearances and lash adjusters are the same as the older engines that took 5W30.
