Just picked a new toy/daily driver, So my'01 burban can "rest" as a backup/work vehicle.


It's a '08 Crown Vic EX-FBI car with 180K miles and 400 idle hours


So I followed the "BOIG gospel" and picked up 6 Fram Ultrasyn's XG2 for $25 on ebay and just did a flush and changed oil with Harvest king full syn 5W-20


Only goofy question is any recommendation on oil since it went from a warm dry climate in Riverside California to a "PMS/BI-POLOR" climate here in OKlahoma, One day its 35 next it 80 smirk


Thanks in advance folks !!

Dave

I run Maxlife high mileage 5w-20 synthetic and a Fram Ultra for at least 10k. No issue that I can tell.

In my moms 03 Crown Victoria 4.6L I have been using Mobil1 5W 20 with a Mobil1 filter for 1 year or 10k OCI, My brother always buys them on sale together and I change the oil for her, car runs great!

Sheís got a cop engine, cop suspension, and cop tranny. Itís like having a Lincoln without the payments.

An idle meter! Cool! Itís totally possible it has Kevlar ballistic panels in the doors.

The severe service owners manual says ď do not exceed 100 mph for the first 1000 milesĒ.

5-20 is perfect. If it burns a bit of oil, 5-30 can help. Also, change out the rear end fluid. Supposed to be full synthetic. The engine wonít notice the climate. Every day is a hot day for it.


If you want the job done right......do it yourself.

IIRC the 4.6 was back spec'd for 5w20, so it would have no problem with 5w30 especially in a warm climate....agree that Maxlife and 10k intervals will go well with your Ultras used for 2 OCIs...you could try other oils but that's a good combo.


I'm a thickie; but a 20 has its place.

I use AMSOIL‚ĄĘ

Actually, itís interesting, it wasnít a back spec. The 2008 owners manual called for 5W-20. smile

Magnatec 5W20 & Fram Ultra does great in my 4.6, just ripped off a 450 mile trip up here to Rockford IL with it Monday, no consumption whatsoever. Ashamed to say I only cracked 100 once!

Yeah smile Nit picky. I used the term "back spec'd" to denote that the engine was unchanged but the oil recommendation changed due to CAFE stepping in...previous years the 4.6 used 5w30. I don't know which year they changed it for the first time to 5w20.

That was a great question. I just checked the owners manuals for the Crown Vic and it was 2001 when Ford changed from 5W-30 to 5W-20 . Wow, thatís 17 years ago. smile

+1, hard to beat the price on that without having to deal with rebates. Plus it's a step up from the Harvest King syn-blend 5w20. Although I'd prob switch over to a 5w30. Same price.

"Wow that's 17 years ago". I haven't noticed Ford engines failing due to excess wear. At least I haven't with my own engines. shrug
