Who's putting miles on their 13-14

So who here as got "high" mileage on their trinity cars? Is lower mileage considered higher on these cars because of the plasma lining?

I ask because I'm in a dilemma.

I live in Maine, so my car is safely tucked away from the damned white stuff we suffer from up here. But as soon as the salt is washed off the road, you can bet she will be out and running. But last week I switched jobs, and instead of being about a mile away from work, Ill be 31ish or so miles away. This raises a mileage concern for me and my desire to drive my car every day.

Sitting on 43k miles now, ill realistically put 10-12k on her this year. I'm not so concerned with value as much as reaching 75k miles and the trinity tapping out because of the plasma lining in the block. Obviously that would require a bit of a crystal ball to know when something might fail, and that's not what I'm asking.

Maintenance will always be 110% with me on her. The car might see the 1/8th on street tires twice a year, other than that just street driven. The car is also currently pretty healthy too. It put down 613hp, and 615 ft-lbs this fall. Only mod is a Borla catback.

Any advice or warnings such as be prepared for a rebuild at 90k? keep it under 100k? 80k? Should I just bite the bullet and make it a weekend/perfect day driver to keep my check book safe and mileage down?

I know Shelby said to drive the cars, and that's really what I want to do!

I've always been the believer of having an everyday car. I prefer to use the Shelby for evenings and weekends. Less worrisome about some idiot door dinging my car in the parking lot and putting all the excess commuting mileage on her. Daily driving a Shelby can be done tho...

I just bought one at 50k. Step dad is the go to shelby and Ford GT mech over here amd usually has anywhere from 3-6 KR’s, Shelby’s, gt Car’s sitting in his driveway working on them for people. He knew the car I bought from The day it came off the truck to the day I bought it and said he sees them run much higher mileage with good diligent maintenance and care

I just hit 8k miles on my 14 Shelby and it probably won't go much, not because I don't want to drive it I just don't have free time anymore. I usually take it out Saturday for a little and that's about it. At this point the goal is to pay it off and keep her for the rest of my life. Hopefully I can eventually park a S550 GT500 next to her

I own several other vehicles, so its not that I don't have anything else to drive, its just that I don't want to, lol. Not worried about it getting beat up at work, as I'm a manager at a car dealer, and generally get to park close to the building. My car is also something that I bought wrecked with a salvage title, so its not like a top of the list collectable car, even if the options are pretty low numbered with the glass roof option.

If I had an 8k mile virgin, I'd probably do the same. But I sought out a wrecked one so I wouldn't be worried about driving it all the time. But I was also substantially closer to work too. I drove the wheels off the car after I got it done in September this year, and even with an 850 mile road trip, only managed to put less than 3k miles on it. Now its potentially going to have substantially more miles on it that before, in just a 5 day work week.

I'd love to find a twin, one with next to no miles to park next to her, but that's not in the cards currently. Hell, if I can finish my 68 T-bird, or my 91 ranger turbo swap, id probably not worry about the miles as much. But with my lack of free time, those may be another year before they hit the road.

Wrecked salvage title... I wouldnt worry about it... Worst case scenario rebuild the motor. I would just drive and maintain it and not worry about mileage...

"High" mileage is somewhat subjective. Relative to @2011 gtcs, the ~27K miles on my '13 is "high." Relative to your 43K miles, is "low."

My use mirrors @Totalpkg, with a daily driver that lets me reserve the Shelby for "pleasure" trips, primarily on weekends. I'm not worried about engine problems as much as I worry about weather (i.e, hail), road rash from gravel, and idiots who don't respect others' belongings.

I don't save my car for the next guy. My Shelby is a second car, however I love to drive so I do. I don't go far, so miles do not rack up. However, I don't worry about these motors are perfectly fine going to high miles..

Yeah 27k still isn't bad. My silver 14 GT500 had only 5,100 miles when it was totaled out.

My 2013 just turned 25k and makes ~ 780rwhp. Been daily driving it since I bought it w 6k on the clock in Dec 2016. I use Mobil 1 oil/filter every 3k, fresh NGK Tr7ix Iridium spark plugs annually, and drive it ~ 8k per year zero issues. Love it! Have no concern about the motor given I am diligent w the maintenance and responsibly use the power.

Miles? Call me crazy but I have only put around 900 miles on mine from the day I purchased it New. Both of my cars never made it out last summer just no time and living in the Boston Ma. area with snow salt and sand makes it even harder.... Would love to be with the sun shinning 12 months a year!

I've got +- 6k miles. Bought it new in July of'12.
Having other cars & too many projects & other hobbies limits drive time.
It gets aired out every time I take it out though. At this rate, it'll be a relatively low mile car for the rest of my days.

I don't think the plasma sprayed bores are a cause for concern with respect to mileage. I have no evidence to support this, but I'd guess these motors are good to 250k plus if they are maintained and not abused. If you're not concerned about hurting value/adding mileage to the instrument cluster, I'd argue that going from driving 1 mile a day to 30 is not necessarily a bad thing. Now your car gets fully warmed up, all of the condensation in the crankcase gets burned off, the gas in your tank stays fresher, etc.

I bought a 2004 5.3 Yukon from a coworker/friend a couple of years ago to use as a daily beater. The guy lived less than a mile away from work and the truck had only 75,000 miles on it. I got a good deal on it, but it was junk by 90,000 miles. The short trips every day with no warm up killed it IMO. Oil pressure eventually fell off to less than 5 PSI, and I couldn't fix it without rebuilding the motor. I should have known that, but I didn't care I guess because it was so cheap. Lesson learned.

This article says it's more durable than conventional bores:

Shelby Block Tech: Ford’s Plasma Transfer Wire Arc

"... according to Tim Beyer, the cylinder walls are also extremely durable. “You can’t bore a block with the PTWA the way you would bore a conventional block, because the coating is only the thickness of the human hair,” he said. “There’s no material to overbore, but the coating is tough and simply doesn’t wear out. We’ve gone over 200,000 miles in durability testing and the block still has the cross hatching.”

“The PTWA really holds up,” added Palazzolo. “What we laid down originally is often better than what you’d get with a new hone. When we rebuild we’ve not seen bores we’ve had to fix up. Cast iron is softer and you’ll benefit from honing to achieve fresh cross-hatching, but with this material the cross-hatching is still there. The material contains a very small micro porosity so there’s oil retention built into the material. If you haven’t failed a piston and/or gauged things up, the bore is suitable for rebuild just the way it is. It is a thin coating, so if you fail a piston and score the cylinder wall, you will want to start fresh with a new block,” he explained. “When you design an engine with 0.020-inch or larger overbore capability you’re carrying that material around the life of the engine and you may never use it.” "

1. PowerTrain: 5yr/60000mi ".....so Ford thought it was good for @ least 60K !

That's kinda what I was looking for! Glad to know that ford expects the lining to hold up! I remember some of the old Cadillac linings that were known to have problems by 100k miles or so, and I was afraid this was the same stuff. Great post bud! Thanks!!!

I've had several high mileage highway vehicles and several low mileage ones too. The constantly driven ones seemed to hold up better in my history with vehicles too. I've got a 7.3 excursion with 346k miles, and its never been opened up, and runs like a champ!

OP drive the car and dont worry. The engine isnt gonna fail at 75k. Keep up with the maintenance and use good gas youll be fine.

My other vehicle is a 97 F150 5.4 with 290k and that’s seen much harder miles than these Shelby’s haha

Mine has done more sitting than the previous year since I bought it.

Bought it 2 weeks after my first born. Put almost 4,000 miles in it that spring/summer of 2012.

Average mileage keeps dropping, busier every year with work, having our 3rd monster this weekend... just no time to do anything other than drive to the store or grab a bite to eat.

Doesn’t even have 15,000 miles now. But if I was single with no kids, I’d DD the hell out of it.

Didn't you get your car early on? I was thinking you were the first one here to actually get one home.
