    Hey Guys,

    Conventional wisdom says forced induction will lower overall engine life, period. However, with factory forced induction and all the engineering that goes into these engines, do you guys think conventional wisdom still applies? How far can I expect my stock Fiesta ST motor to go if properly broken in, maintained, and driven how a FiST owner drives (you know what I'm talking about) ;) ? 100k? 150k, 200k? Discuss.

    I've been wondering the same thing actually. And how do all the bolt ons we add affect it.

    From everything written about the Ecoboost engines and all of the promo pieces Ford has done on their torture testing, I would expect a long time. Mileage? It all depends. My guess is that they will last a long time and the fact they are turbocharged won't be a factor. If it's your daily driver and you autocross it on weekends and maintain it properly you will get tired of it and trade it in before the engine wears down...

    I just went through the ST Octane Academy where the cars are driven hard and up to redline everyday. I am looking forward to contacting the guys at the Ford Racing School at the end of the year to see how they held up to the many weekends of noobie drivers flogging them around.

    BTW, put the ST Octane Academy on your have-to-do list! It was a great time, lots of driving and the guys there are the best!

    As a side note, and I discussed it here before, the Ford Ecoboost engines are pretty sturdy.
    Contrast that with the 2010+ VW GTI which has an inherent oil pressure defect where the pressure drops below 10 psi under lateral loads, as I found out last year when it spun a bearing at 32,000 miles. The GTI is half again more expensive and not nearly as much fun....

    I fully expect mine to be good for 150,000 + miles. They've been engineered to be boosted. It's not like some hot rodder taking an old
    Chevy 289 and adding nitrous, or turbos and not doing a thing to the bottom end. I'm using my car, but not abusing it

    I'm going to maintain my car like it's going to last forever. I'm not an engineer, but I am going to proceed on the basis of the thought that the engineers responsible for the engine designed it well, and to handle the stresses that the stock engine can produce/will experience. Significant modifications could of course change that, but I don't plan on much. Mine is my daily driver and I'm taking up autocrossing it, and I anticipate driving it for quite some time. As with all new models, only time tells for sure, but I hope & believe we've got something special here.

    I put over 100K on a '04 Mini S before selling it.
    The new owner has had it since '11 and couldn't be happier.

    Like most modern engines, it'll last longer than the rest of the car it's in.

    My question is how long you guys thing this borg turbo will last?

    It works real FINE,
    It will last a long TIME.
    It won't RUST, BUST, collect DUST,
    And it's Sailor Proof.

    My FiST replaced my Audi S4. I donated the Audi with ~240,000 miles and the original turbos. I expect quite a few miles out of the Ford.

    Wow. Sailor proof, eh? Didn't realize the testing had been so stringent. It oughta be good for at least twenty years, then--minus about nine months X2 for a couple of yard overhauls.

    i searched this several months ago. the turbo is tiny. also found on one of the vw diesels. and is replaced a lot. comments on folks replacing the turbo is its not very robust and when pushed hard can wear out or break.

    i am very interested in upgrading my turbo once decent stock location products are available. once reason is above, the other is i want a bit more (conservative) performance, especially a bit higher in the rpm band where the car seems to run out of breath. it has great around town quickness but lacks a tad on the interstate if you are doing 70+ and want a bit more oomph to get around a car.

    for those running tunes especially with a bigger down pipe and exhaust, you may see problems with this turbo as you push it past its current level as from what i have seen and heard its pretty much maxed from the factory.

    Only needs to last long enough for the RS to come out!

    Looks like Castrol's oil change interval is a lot less than Ford's (for their warranty). They want you to buy lots of their oil...

    This is why I change oil every 5K and use full synthetic.

    Is full synthetic the way to go? and will it hurt me to change every 3000? I'm new to turbo engines and the fiesta st is my first. I love it more every time I drive it. any advice would be much appreciated.

    The advantage of full synthetic is that is doesn't break down as quickly, if at all, so the service interval is longer. The only ones recommending 3000 mile oil changes are those who stand to profit thereby. Most synthetic oil makers say 10,000 intervals are just fine, while Ford recommends 5000 min, and up to 10,000 depending upon usage, but in no case to go longer than 1 year, with six months the recommended. (IIRC) ..

    My plan is go go by the book, and have all servicing done by the dealer using six month intervals, or when the vehicle report tells me that it's time. If I were planning to change my own oil, as I have in most other vehicles, I would be using Mobil 1 or Royal Purple, at no more than 10,000 mile intervals, 6000 being the more likely.

    My two cents.

    You could conceivably get as many opinions on this subject as there members of this forum.
    My own rational? Since Ford engineers think that this engine can go 10,000 miles between oil changes with their stock semi-synthetic oil, then I believe that I can certainly go 10,000 miles on a full synthetic. If you do a lot of romping & stomping with foot-to-the-floor acceleration, like this car encourages, then shortened change intervals would be justified. But if most of your driving is commuting and no racing, then the full 10,000 should be considered.

    My $0.17 (due to inflation): oil changes are not terribly costly. My wife spends more on a haircut. My car is important to me, and I want to take good care of it. Upon starting from that point, I find it simple to justify oil changes as frequent as 5-6000 miles. I know of no maker who recommends oil changes more frequent than that for routine driving duties in most areas of the U. S. But, should one be driving the vehicle particularly hard, then a shorter (3000 miles or even smaller) interval can be considered. If I change the oil every 5000 miles and own the car for 100,000 miles over 8 years, then I'll have paid for 20 oil changes for the car over that 8 years. Let's say each is $50 (just to pick an easy number). That becomes $1000 spent on maintenance over that time. If I only changed the oil every 10,000 miles, I'd still be spending $500 for this particular maintenance item. Is the additional $500 worth it? I think it is, and my vote is the only one that counts. Other than my wife's. ("Your hair looks really nice, dear.")

    My goal is not to do as few as possible, but to do them frequently enough so as to take good care of the car. Since I do drive my car hard at times, my oil change frequency will likely be between 3 and 5 thousand miles over the long haul. I'm nearing 3 thousand miles on the odometer, and the car will likely get its second oil change (after doing one very early change at about 500 miles) this week.
