Oil Change & Break-In


Recommended Posts

I've got an '05 GT LTD 5MT that I purchased in July '04. I changed the oil a few months ago and removed an AA080 and replaced it with an AA080. I was at the dealership last month to buy another filter, and they gave me an AA100. :confused: I questioned this but the guy behind the counter showed me on his computer that the AA100's replaced the AA080's in December. I have not installed the AA100 yet because I want to know what the right size should be. Thanks, E

Being right off the deaer's records, I wouldnt worry about it, but yes, the p/n changed. Here's a thread on NASIC discussing it (go down at least halfway through the second page to get current): [url]http://forums.nasioc.com/forums/showthread.php?t=434057&page=1&pp=25[/url] There are a number of filters that fit the car in various lengths and diameters. All that really matters is the threaded hole and the gasket size.

Do a Search on this forum for "break in" (and variations thereof) and you will find more opinions than you care to read on the subject! If it matters to you, follow the recommendations in the owners manual. If you are like many of us who beleve in the "break it in as you're gonna drive it" method, and have had excellent, great-running cars in the past from that method, don't worry about it.

Here's my break-in process for my last car, and Evo VIII. I went through the gears a few times at full throttle in the first few miles, then took it easy (under 4000 rpm, no more than half throttle) until 750 miles. then I began driving the car normally. First oil chnge at 3000 miles. It dynoed at 234 whp 249 torque at ~2000 miles. I will be following the same process for the LGT.

i'm new at this.. so.. when do you start driving the legacy hard.. and what's the break-in thing.. is that when you're supposed to drive hard.. and does it matter if it's a AT or MT?

Went to synthetic oil at the first change at 1,700 miles. Now at 14K, the car runs great, and m porky Limted wagon got easly into the 13.90s with a Stage 1 AccessPort.

i agree with throttlejockey it seem not an easy break in is the better and funner way to do it. that site had a lot interesting info. [url="http://mototuneusa.com/break_in_secrets.htm"]http://mototuneusa.com/break_in_secrets.htm[/url]

I bought the car with 120 miles on it I redlined it test driving. I redlined it a few times already changed to mobile 1 the day I bought the car. all this break in stuff is getting me nervous. should I go back to dino? I'm at like 300 miles now. Someone tell me something quick before I do something stupid with the car.:mad:

FWIW, I have done the hard break-in on every new car I've had since 1978. And each of them has been a strong runner compared to other similar cars. Coincidence?? I think not!! FWIW, my heavy LGT Limited wagon, with a 50-mile Stage 1 reflash (it takes a good 100 miles to really get the performance) and my heavy 210# ass in the seat turned a best of 13.90 in 72-degree, humid weather. Three of the five runs were in the 13.9x range. When I run again in late October in (hopefully) cooler weather, with a settled-in reflash, I expect easy 13.7x runs, with "maybe" a high 13.6x on a stock LTD wagon. BTW, I went to Mobil 1 at the first oil change at 1,700 miles. The dragstrip was done with 10K on the car.

IMO, if that is doing 'exactly what the car needs' why doesn't it state that in the manual? However IMO, based on all the anecdotal at best evidence to support either a gentle or a 'drive it like you stole it' breakin, it probably really doesn't matter a whole lot either way.

If you need to read the owners manual for the advice, they will tell you exactly what they want to keep themselves safe. Follow the manual if you will.....but if you line up with me at a light, expect to get your ass handed to you!! :D Every mfr puts this crapola in their owners manual.

I would expect that if there was something inherently wrong with a gentle break in that the manual would therefore NOT specify a gentle break in. Furthermore, if breakin was such a huge issue, I would expect it to be done in the factory in a controlled environment. I remain unconvinced that either method is either more or less benificial than the other. If someone can show me verifiable scientific evidence to the contrary, please do so, I'd be very interested to see it. Since you've apparantly upgraded to AP stage 1, I'd expect you to 'hand my ass to me'. Plus, I've a ways to go to master the correct AWD launch technique with a MT.

Who is going to spend the tme to do a controlled test. Pat Bedard had an editorial on it around 20 years ago where he discussed it with a Ford engineer. they were gong to pull & analyze an engne in a Mustang GT that was driven (abused) by the press corp. The Ford guy said it was the quickest and loosest 5.0 they had ever experienced. FWIW I have now run a 13.61 with only the AP Stage 1 in my heavy Limited wagon. A buddy of mine is also a convert, as he broke in his new Hemi Charger hard, and has turned low 13.80s in bone-stock condition with his 265#s behind the wheel (a good 3/10s quick than times on similar cars). You could call these "good cars" from the factory, but this has happened to every one of my new cars since the late '70s Coincidence? I doubt it.

^ +1 It's all just anecdotal stories as far as I'm concerned. Until somebody does this to tens/hundreds of cars and checks the engines after significant mileage, it's really up in the air.

Whatever. As you buy new cars over the years, and break them in according to the very conservative factory recommendations, don't post questions as to why your car doesn't run as well as other similar cars. As an old fart, i've been responding to Internet lists/forums for many years as to why my cars (and others) run better than other cars. In EVERY case, we have seen a difference in break-in. Scientific? No, but it is absolutely clear in my mind that it works. FWIW, I also had a long-term test with an '89 SHO that I bought new. I hit the 7K redline multiple times every day of it's life (I believe the term is "I beat the snot out of it")....and I sold it 10 years later with 182K miles. I religiously changed the dino oil every 3K. Oil consumption was a quart every 2,500 miles, down from less than a quart at every 3k change. My buddy is the new owners and he ran 14.8x ETs with a slipping clutch at about 190K miles. He stll has the car. the body is rotten, but it still runs strong with about 210K on it.

[quote name='moviemadness']I thought synthetic was better...?[/QUOTE] Better than what?? ;-) FWIW, I will always stay with dino oil on n/a engines. And I will always stay with synthetic on turbo & supercharged engines due to the better heat resistance.

[quote name='moviemadness']I hope you have a good convincing arguemet for the ongoing debate on the issue: "Synthetic is too slippery for new engines and you should break in on dino for newer engines for the 1st 1k miles"[/QUOTE] As was mentioned in one of these threads, the "Synthetic Is Slipperier" is an OMT (Old Mechanic's Tale). Not true, that has been a rumor that has floated around for years, and just won't die. it even comes fro the mouths (and keyboards) of people who should know better. Synthetic has better heat and wear resistance, to put it more simply. "Slipperier" is not an attribute. Break-in is a non-issue. OEM mfrs use it in certain cars from the factory.
