Ok...the difference of oils.
Between Mobile 1----Valvoline----Castrol GTX
Which do you perfer? and why?
My last car I always used Castrol GTX but I see quite a few here like Mobile 1.
What about the oil filters? Fram----Mobile 1
Which do you perfer? and why?
One more question? How long will unused oil and oil filter be good for if I bought and just kept in the garage on a shelf. ***I know it would be awhile but how long?
Thanks for answering greenhorn ?'s. lol

Mobil-1 is a Synthetic. The others are Dino oil out of the ground.

I use K&N Oil filters. Don't have to bother with oil filter wrenches. Just need a 1" Wrench and you're set. I was using Mobil 1, but I was paying $36 for 6 quarts... and I get the same 6 quarts of Royal Purple from American Muscle for around $32-33 with the Mustang forums discount. Plus free shipping and it usually gets her in a day.

I use Mobil 1 full synthetic with a motorcraft filter.

I use a Penzoil filter and Castrol GTX oil when I change it every 3000 miles.

The oil cost's $1.09 a quart (bought in case qty, after rebate) and the filter is $4.99.

You dont need an expensive filter or synthetic oil if you do it that often.

I have always stuck with Motorcraft, then again I'm not pushing much more than factory HP, and change it every 3000.

for the royal purple, is it the same 5w-20 or is royal purple synthetic oil?

Alloyed

I use Mobil 1 full synthetic, and a Mobil 1 oil filter. It's in all of my cars, I swear by it.

I think your line of thinking is in the minority around here. Synthetic oils reduce friction, improve power and fuel economy, and dramatically increase engine life. After 100K miles, let's take your engine apart, and then the engine of someone running Mobil One etc...the engine using synthetic would still look new. Also, Ford's factory fill is a part-synthetic so you're running your car on sub-standard oil. Look, maybe I'm being a d!ck and I know it's none of my business, but don't you think your baby deserves better? I use mobil one 5w20 and mobil one filter, will change it every 3mo./3k, yes maybe it's overkill but I am absolutely in love with my car (sappy)...sorry if I came off preachy...
