First off, I'm sure this has been asked before. For 2571's first oil change I'm not sure if I should go 5W20 Petrolium Oil or go to 5W30 Mobil 1. I've been told that I should wait till after ~ 6000 miles before going synthetic. Is this true? Any help would be great.

Thanks

Funny you should ask?
Last weekend, at car show here in the Tidwater area a Ford rep was there pushing Ford technical training and he said keep using the 5W-20W oil, it's what the engine is built for I asked about 5W-30W he said it won't hurt, But he recomended th 5-20w stuff. I didn't ask about syn. Sorry

It figures the rep would say that's what the engine was built for. The 4.6 has been out for 6+ years and Ford now decided to tell us 5W20 is the right way to go, I wonder if there's something that they're hiding.

Ford claims that the lower viscosity rating is to get lubrication to the heads faster. Not to mention the supposed better mileage for their CAFE rating.

The top end lubrication claim really doesn't hold up. If the oil temperature is such that 5W20 is acting like a 5, then so is 5W30. The 30 only comes into play at the higher temperatures, like Houston in the summer, Death Valley, etc.

The manual recommends the 5W20, but also states that any oil labeled with the API seal "For Gasoline Engines" is acceptable.

I've been using Mobil 1 5W30 since 886 miles, and I right at 2000 tonight. Nothing alarming to report, and the engine feels stronger with every mile.

I've got 900 miles now. I think I'll do my first change at 1000-1200. I bought 5 quarts of 5W20 Premium dino oil from Ford with the exact filter they recommend. I'll use it this time, and possibly once more at around 2000-3000. I like having the receipts from Ford that show I bought the oil they recommend. It will make any warranty discussions that much more in my favor (god forbid.) I'm going to switch to Mobil 1 when the engine feels as strong as it will get. I figure that will be around 5000 miles. Then it will be Mobil 1 forever. It blows away dinosaur oil.

I'm switching to Mobil 1 5W-30 at my first oil change. A few years back my family and I road tripped to New York to visit relatives. On the way we stopped at the Corvette plant and took a tour. My Dad was speaking to one of the tour guides about the ZR-1s that were showing up for sale with low mileage and how he was considering one. We were told that they were regularly seeing 40,000 mile ZR-1s with engines that had not yet fully broken in because their owners had used Mobil 1 religiously. I like the idea of driving my Bullitt for a long while and still having an engine that is just settling in. Of course, I'd like a Z06, too, but I'll take what I can get.

I changed my oil at 2500 miles ( currently 4600 miles) and after much thought, went with the mobile 1 snythetic 5w-30w and it's ran just fine.

I found Ford Motorcraft 5w20 syth-blend oil on the shelves at my local Wal-Mart. 1.77 per quart.

Ford sells a Syn-blend? Then maybe the synthetic is already available. I feel more comfortable using Ford parts, just in case they come back blamming the oil I put in.

I think for my first oil change I will stick with ford's 5w20 oil because the dealership I purchased my Bullitt from gave me a coupon for the first oil change and $10 off every oil change after that. I can't argue with that.

I went with Amsoil 5W20 and Purolator Pure 1 filter at ~1600 miles. I will change the oil again and switch to an Amsoil filter at 3000, and change it every 3000 from then on... I find the "just settling in at X0000 miles" idea to be appealing as well... I've got a bypass filter on my wish list as well. :smile:

I may really wrong on this but,
1: I thought it would be best to run non-synth oil for the first, say, 6000 miles so the engine can be broken in. I figured synth is too slick to let this happen.
2: I thought we wanted our engines to "break in". Don't they run better once that happens?

Beware, Anumis. When I went to my Ford dealership for my free oil change the guy tried to put in 10W30. I stopped him just before he started to fill it up. He acted like I was really putting him out when I told him I wanted 5W20 put in. Keep your eyes on 'em!

I too found the Motorcraft 5W20 sync/blend on the shelf of my local WalMart in Hanover Pa. For $1.77 a qt. Couldn't buy it by case though. I had to buy 12 loose bottles. I hope Wal mart continues to sell it!!

I think you're right, Y2K16T8. #2066 is getting stronger and stronger as time goes on. I guess that means it is breaking in well.
