New Marauder owner (2003) oil question

[Rookie_FitItMan]

Howdy! Brought home my new (used) 2003 black beauty this weekend. 38,000 miles, very clean, stock. Read the owners manual last night. Mobile 1? Amsoil? 5-20? 5-30? Any/all opinions welcome.

Anyone here argue (debate) with the Crown Vic folks running Police Interceptors - PI 71. Marauder better? Badder?

Rookie, I don't think the Crown Vic folks will argue with the statement that the Marauder is both better and badder than a P-71...the main differences between the P-71 and the base CV are that the P-71 has many parts that are heavy-duty and it has slightly revised PCM programming, mostly to raise the idle speed & speed limiter, and to alter the shift characteristics. There is no mechanical difference in the motor or transmission between a P-71 and any other CV/GM. The P-71s don't have a "cop motor", and unless the PD deliberately had one installed, there's no special "cop chip" in them, either.

BTW, check your PMs...

Welcome to the Collective, resistance to moding is futile. You will be assimilated.

And welcome to the Capitol Area Marauders (CAM) and just in time too. We are have our June Meet this Saturday, check out the thread in the Northeast Forums. Come on and join fellow Marauder owners eating some good food and BS about our cars and kills. Hopefully Bigdogjim will be there to tell you about his stealth mode, hope you can make it.

I've tryed Mobile 1 5w20, Amsoil 5w20 , Royal Purple 5w20, And Fords factory 5w20 oil. And I just like the Mobile 1 Syn the best, But I do use the Amsoil Oil filter,if you read some of the thread's on it it's a really good filter.

Mobil 1 5-30 is my choice. Last car was a 2001 CV P71. The P71's have 16 valves vs the 32 valve Marauder. My P71 was quicker than the Marauder but put out less HP.. I had a K&N intake and flowmasters, but the big difference comes from the transmission set-up. At WOT the cruiser stays in second gear until 95MPH. The tuning guys for the Marauders change the shift points--makes sense.

If anyone disputes the above, just pass a highway patrol car at about 80 and step on it to see if he can catch you--Hank

5W-30.

use 5W-20 if you want to wear out your engine. Ask any Ford engineer that knows half a sh-it about engines, you won't hear any recommendations 5w-20 unless legal is on their ass.

With it being so hot here in Central Florida, I use 10W-30 in my cars. (If I could not get 10W-30, I would use 5W-30). There is no way I would use 5W-20.

I have never been "Loyal" to any one brand of oil, however I mostly use Mobil-1. At the moment, I have Mobil-1 in my Continental and AmsOil 10W-30 (Group IV PAO) in my Marauder (only because I got six quarts of AmsOil from a friend at a price I could not turn down). Sitting in my shed is seven quarts of RedLine
10W-30 (Group V ESTER [Polyolester]) which I purchased at Advance Auto Parts, when they decided to not carry it any more. Got that at a very low price. Also have five quarts of Mobil-1 10W-30 (have not been able to get an answer from Mobil if their synthetic is still a Group IV PAO or if they downgraded to a Group III "Hydrocracked" Synthetic, like most other "Synthetics").

Next time either car needs an oil change, I'm not sure which oil I will use.
