I've got an 03 GMC 5.3L ext cab Z71. 205,000 miles on it. Replaced water pump and both catalytic converters. That is it, since new.

Wife drives an 07 Chevy 5.3L crew cab Z71. 80,000 miles on it. We have put tires on it.

Her's is supposed to have the V4/V8 mode to give better mileage, blah blah blah. Hers gets the same mileage as mine, just right on the nose 16 mpg.

Mine uses absolutely no oil between changes, hers will burn a quart in 3,000 miles. Same as a contractor I use that also has an 07. Same as has been referenced on this forum, and GM just says 'tough'.

For kicks I just did a google search.

Typed in 2007 5.3

Google tries to autopopulate as you type, the third thing it was trying to auto-fill in for me as I typed the 5.3 was 'oil consumption', think it isn't a widespread problem?

Silverado 1500: As for Chevrolet's larger trucks, a number of enhancements will help make the Silverado more fuel-efficient and thus more competitive with the Ford F-150. We've heard GM hopes to shave at least 500 pounds per pickup truck by 2016, all while retaining the content and safety features mandated by buyers and NHTSA alike. We wouldn't be surprised if the new trucks use more aluminum, magnesium, and other lithe alloys in order to achieve that metric. New powertrain designs will also help cut fuel use. GM's next-generation V-8, which will feature direct fuel injection, E85 capability, and a reported "advanced combustion design" will likely be one staple. Other reports suggest other six-cylinder engines are under consideration, including a turbocharged variant. As with the Tahoe/Suburban, an eight-speed automatic transmission � perhaps the very one scheduled to be built in Toledo, Ohio � and an evolved version of GM's 2-Mode hybrid are expected to be offered. Don't expect these revisions to happen overnight, as GM executives have previously indicated the company won't rush the line to market. As it stands, expect the next-gen Silverado to debut in late 2013 as a 2014 model.

Silverado 2500/3500: GM extensively reworked what's beneath the skin of its heavy-duty pickups for the 2011 model year, so now it's time for a cosmetic reboot to match. An overhaul is expected to arrive in either model year 2014 or 2015. We're also told a successor to the popular Duramax 6.6-liter turbo-diesel V-8 should arrive around 2015 or so.

The Tacoma has alot going for it, especially when it comes to being reliable and cheap to run and maintain. I'll add one more. It's got a true locking rear axle option which comes with their off road package. They work alot better than any of the limited slips that all the others offer. E

I have a 2010 F150 5.4 auto 4wd with 13,000. When I first got it when not all stations were cutting their gas with 10 to 15% ethanol I got 18 on and 17 around town now I get 16.2 around town. It sits in the garage most of the time and I use when I need a truck. With a 60 mile round trip to work I run an escort. Love the truck and the ride.

It's not a truck, but the family wagon '09 Chev Suburban was a lemon from 17k miles when we bought it. Auto door locks, Power windows, and axle seals, all covered under warranty. It was in the shop every 2-3 months that we owned it.

Once out of warranty it started overheating sporadically. That broke the camel's back so to speak.

We traded it off for an older Suburban with the same mileage.

I think we got a vehicle that was built by some bummed out workers during the GM Bailout.

well

9 outta 10 sales managers aren't going to waste their time giving their best price over the phone. I'm sure the salesman would love to help you, but it's a simple fact that the sales managers just aren't going to take anyone serious over the phone. [/quote

Well got a quote from sales manager and he told me his price and I drove out and we did business. No funny stuff, got a fair price for my trade in and the transaction was completed within 2 hrs. truck was detailed durning the process. Will recommend the dealer and this sales manager to any one in want of a Toyota in my area.

I had a 2000 Yukon XL with the 5.3L that gave me no problems in 186K miles. I replaced it with a 2007 model, with a "newer generation" 5.3L: I bought it at 40K, and just clicked over 70K. The SOB uses about 1� quarts of oil in 3000 miles, and the dealer won't do anything about it since GM's spec is 1 quart in 2,000 miles. I've never owned a vehicle that burned anywhere near this much oil.

I was done with GM cars many years ago. I'm done with their trucks now, too.

Were I looking at a pickup, I'd choose between Toyota & Ford. For another Yukon-ish vehicle? I have no idea.

I would not be happy with that much oil consumption either. Wonder what changed between 2000 and 2007 to cause these issues? Seems like a lot of the excessive oil consumption complaints are from the 2006 -2007 year models.

Thanks for the replies!

toyotas suck ,period.

buy american. and don't tell me toyota is american. what a joke.

Went to one Chevy forum that discussed the oil consumption. About a 10 page thread that goes back to 2008 when people first started realizing their 2007's were burning a lot of oil. The general consensus is the engine that switches from V8 to V4 mode is the issue. GM has a big long decision matrix on what to do when a customer comes in with this issue. First they say 1 quart in 2000 miles is their spec, problem with that is they changed it from 1 quart in 3000 miles when the issue first started. Next they'll put a 'deflector' in the engine that keeps oil from splashing on the cylinders that get shut off in V4 mode, something about this oil builds up on cylinder wall and when its reactivated the oil goes out the exhaust valve. When that doesn't work they'll do a couple of things, have heard they'll tell the computer not to go into V4 mode, have heard they'll put new rings and pistons in. Most say that this solves the problem for only a certain amount of miles before it comes back, basically GM doesn't have a solution, they're grasping at straws and trying to act like they're doing something. Nobody said what they do after the rings and pistons, but several said it didn't solve their consumption permanently. Google it, many many many boards discuss the issues with all the same conclusion.

Glad I got an 06! FWIW it's a crew cab short box Z71, and I've used the crap out of it. Hauled a lot more than I should've with a 1/2 ton, but it's done great. I should knock on wood after saying that. On highway with a tailwind I've gotten 22 mpg, but if I keep it to 60-65 I can get 17 running around here. Get too deep into it and I get 15.

A friend of mine had the same issue with oil consumption and lack of fix from the dealership with an 07 suburban, finally gave up and traded it off.

I kinda miss my '06 Sierra Z71. Alum. 5.3L. No oil consumption issues at close to 50K when traded and it got better mileage than the '10 Chevy w/4 cyl. doohickus.

Really miss it when blending into interstate traffic. That thing was a friggin' rocket, compared to the '10.

Something to be said for a 82' k25 Chevy with 350 and a TH400...

Just sayin'

GM used to make a good truck....

Very insightful and helpful opinion!



Thanks to everyone who posted actual experiences with the trucks I asked about. Will probably go drive a few trucks in the next few weeks and make a decision from there. Been reading from several different rumor mills that GM, Ford, and Toyota wil be offering engines with direct injection in the near future. May be worth the wait.

Registered democrap union thug? Or just a run-of-the mill dumbass?

Is there a difference?

Good point!

I currently have three Toyota Tacoma's..but I see both sides of the "it's made in America and pays Americans salaries". It is a company still owned by Japanese investors and the profits go there..I think most of the bashers would have a little different opinion if you had spent five years of your life fighting for your life and now sending ANY money their way.. Bash me if you wish..but I can tell you for sure my dad had hard feelings this way and I did not buy anything Japanese while he was alive..Yes, I see both sides of it..
