"Normal" oil usage

[Tank]

Refilling 1/2 your oil every 5k just sounds shady to me unless you are living over 5,000 rpm. If it was 1 for 1000 "with heavy track use" I'd find that more acceptable and even reasonable.

It's twice that under certain conditions....

According to the March 2017 Shelby Supplement pg. 48, oil consumption of "approximately 1 quart per 500 miles" while "driving high performance vehicles in such a way that might lead to higher oil consumption (this includes extended time at high engine speeds, high loads, engine braking, hard cornering maneuvers and track use."
This would not be an acceptable car for you.

You clearly didn't read my signature or what I wrote. A A4 is no more a performance vehicle than a GTI and I'd say less of one than a modded Mach1.

I also text my friend with a STG2 STI and his previous car was an Audi TT 2nd gen. He said that neither burned more than 1qt a change and he changes at 7500 miles.

It's really starting to feel that many of you just accept oil burning as normal instead of questioning it at all when others clearly say they use little to no oil.

Supposedly the average person drivers 15k a year. Going by that why EVER get an oil change when you are literally burning all your oil every 6-8 month and replacing it. Just change your filter.

You read the last line of his sig?

It would appear that you will be rolling the dice, hoping for a 5000 mile per quart car. Which some people claim to have. If you can pull the spark plugs on a 1000 miles per quart car and they appear normal, then it won't be easy to get a read on a used car. If you buy new, then its still a gamble. Maybe break-in and driving habits make a difference, maybe they don't.

Yes. I have, and I have not known the GT500, i6 M3 or 335 to eat oil. My friends brother is a head BMW Mechanic at a dealership and aside from his bike refuses to drive a BMW as his personal ride. he drives Subaru's. I'm quite familiar with how they are told to just say that burning oil is normal even when their techs know that it's not. He will freely tell you that BMW's sholdn't eat as much oil they are told to tell the end customer because most wont keep their car long enough for it to ever really be an issue, or when it does it's out of warranty. It's cheaper to print a line in a manual than fix an issue.

It's amazing that I've never known anyone to have a car that eats oil and find it normal, but some reason people here don't even question it. The only people I've known that ever mentioned burning oil in any of their cars were one that were built to run 10's or lower.


My concern is buying the car, and just allowing it to burn 1qt per 1k or even 3k, then after 7yrs and almost 60K later having some issue due to it that will cost a LOT out of my own pocket. I'd rather question it now, than later.

my car has been using a quart about every 1500 miles. I have been too lazy to acquire a torque wrench and associated tools to pull the spark plugs and have a look. I could take the car to dealership, and ask them to check. Although they could just say its fine and send me on my way. I also thought about having them install brand new spark plugs and having the old ones returned to me, so I can see for myself.

I was trying to help and educate someone who does not know much about performance cars or engines, but you seem to be trying to sell your point here, and I am not buying anything.
Oh, and your mechanic needs to be schooled... He should not be allowed to work on BMW's with that attitude. A BMW mechanic should be proud of his work, proud of the brand. Those engines use oil by design.

I want my 5 minutes I spent typing in this thread back in my life....:frusty:

Over and out.

Did any of you have a normal Coyote mustang before the GT350? My 2011 GT ate almost one quart every 1k miles. By comparison, my GT350 is more parsimonious. 1k every 6k miles is Toyota Corolla land. Or my wife's 2011 Explorer with a 3.6 V6 boat anchor.

I had a 2011 GT and a 2015 GT before the GT350. None of the three burned oil.

Assumption that I don't know performance engines is wrong. So you already started off incorrect.

I don't know what deluded world you live in that people have to love the company they work for to work there or do good work yourself. He actually quite dislikes BMW, but I'm sure the fact he's skilled is what matters more to them. Last I heard he was starting to be an alternate tech for one of their race teams. Not sure which. If loving your company was required to work at a business, then there would be a LOT of unemployed people. Being proud of your work is NOT related to being proud of where you work. He's there because it pays well. He used to love BMW until he spent years working in their garages. Now just finds them full of marketing BS.

He will also tell you that the early 335 should have been recalled due to how often their turbos failed. They were apparently a easy fix they could have done in the shop but he was required to do a full new turbo change even for people that were no longer under warranty. Why? Because BMW wanted money for a full new turbo, not the few $$ it would take to fix the ones that were broken.

if you are really worried about potential for oil consumption, you could just get a GT+PP. If it does require oil, you can use the savings over a GT350 to buy oil. The good stuff too. Not sure what happens long term on 1000 mile per quart cars. Maybe nothing. Maybe the cats will eventually go bad. I think cats are covered by more warranty than the standard power train warranty. Unless you mod.

I've been debating that. It's not the expense of the oil that worries me, its more of the effects, if any, of burning that much long term. I personally only do about 4k-6K miles a year. My Mach1 never had an emissions test in 11 years because it was under the mileage limit every year. I'm just worried and I'll admit, possibly over worried, of any negative effects of it in the long term. I like to keep my cars till either they die or are old enough that I worry about reliability.

GT does have an advantage in that the Coyote has an oil level sensor. So should the car use oil, and you forget to check the oil for a while, it should alert you with an indicator on the dash, rather than a dealership technician saying "your engine oil was <x> quarts low", or worse, unpleasant engine sounds. Although I haven't tested that the oil level sensor to see if it works.

On a related note: where's the best / cheapest place to get a few individual bottles of Motorcraft 5W-50? My local Autozone, Advanced Auto Parts, O'Reilly's don't carry it. I don't want a case, and I don't want to pay $18 a quart.

Aren't they ~$10.00 per quart at your local Ford dealer? They cost about that much in CA, which I figure must be one of the more expensive places to buy.

I know that some people seem to rarely need to top off, but I feel like anything over 1qt per 7500 miles today no matter the engine just isn't acceptable.

The high performance V8 vehicles I've owned typically used 1 qt per 3500 to 5000 miles, depending on how they were driven.

 

[UnhandledException]

S65 M3 used 1 qt every 1500-2000 miles. F10 M5 about 1 qt every 2000-3000 miles.

Vodoo will use absolutely no oil if you just daily drive the car normally. You can quote me but if you redline it and keep the revs high, it uses oil. I think except some outliers, this is the norm.

Track weekend. full of oil at start and full at the end : )
