My 2007 Ford Fusion turned 300K today.

I’ll be honest as a mechanic majority of the oil consumption issues I’ve seen have been on high mileage cars with extended intervals. Can’t completely prove it was the oil change interval that caused it but it seems to be a similarity in all the cars with the consumption issues and no engines from those brands were known oil users so it had to be something to do with it.

Just curious here. How many downright engine failures have you seen in your career that were due to the type of oil & filter and/or how often it was changed?

And are engine failures becoming more common? I heard a guy at a reputable shop awhile back say that he wouldn't trust a new car engine past the 36K mile warranty.

None that I can prove. But I assume that it was part of the issue. As do other techs at my shop. Almost all of them were higher intervals. So it just makes you assume that could be the problem. That’s why I said can’t prove it was that but suspect it. But some we also don’t know the past history of services either.

And I’d say no regarding are they becoming more common. Especially as far as oil technology has come. I think a lot has to do with how it’s cared for. I’ve done a few engines and most have been in older things. Some have also been in newer stuff but there was screw ups that caused it to be changed like someone left the drain plug loose in one. It fell out, customer ignored oil light and blew it up. I just done a Land Cruiser that a dealership 70 miles away only put three quart of oil in and it was pretty bad on the inside so had to replace that one. There’s been more than one case like that. And honestly I’ve only been in the field about 4 years now so I may not have seen as many as some guys have. I do know one thing though is certain brands I definitely see engines being rebuilt or replaced in more often.

I think usually it starts with excess oil consumption, caused by lack of oil changes and then the failure happens after the customer let's it run low once or more.
I had a customer at a previous job that had the sludge prone 4.7 in a Dakota, he had it have the engine replaced (not sure of his previous oci) but he went with 3k synthetic oil changes on that specific engine only, to keep it from happening again.

I think (and hope) the tech I heard it from was exaggerating. He was really upset that a replacement engine had internal problems after less than 30K miles (broken ring, maybe), and the original engine failed at less than 60K miles. He said both were quality issues. He was especially down on GM's "LS" family of V-8 engines.

Hmmm the LS engine was replaced in 2014 (except in vans as far as I know). It had some issues with the cylinder deactivation models from 07-13 but other than that it's a great engine. They came out in 99 (earlier in Corvettes). Sounds like that guy doesn't know what he's talking about. (Doesn't mean he's a bad mechanic).

It’s just crazy to think someone actually believes that oil has advanced that much

It’s even crazier to think some people believe oil hasn’t advanced that much over the years

Tig1 should have a lifetime supply of M1 given to him for his dedication

 

[tig1]

The 2007 Fusion just turned 305,000 miles. I do plan to change oil next week and this 10K OCI in this engine used about 6-8 OZ of oil.

 

[pbm]

Let's see. I had a 1985 Ford Escort diesel that went to 300K before wrecked. A 91 Ford Ranger 3.0 that had 354K when sold. A 1990 Ford Tempo gas with 250K when sold. A 1996 Merc GM with 218K when sold. A 2007 Ford Focus with 175K when totaled. And my present 2017 Ford Fusion with 143K. All these at 10K OCIs with M1 oils and MC filters.

The Mobil 1 sure helps but you have to give Ford some credit too.

I failed to mention my 2007 Ford Fusion with 308K. I drive Fords because I've never had one to fail (engine or trans) to date. M1 and Ford has been a very good combination.

Well said sir

I’ve been driving Fords for over 40+ years
No issues out of my pocket

 

[tig1]

If he has had good luck then that’s on him. Based on the issues I’ve seen across multiple engines it’s safe to say my argument is correct. I’ve seen it on more than he has listed. I’m not blaming Mobil 1 at all but they are a company that’s out to make money so they will tell the customer what they want to hear. And I’m not sure I’m full on 100% about him having no issues but I’m not there so I don’t know for sure. Sure it keeps the engine clean but that doesn’t mean it’s not doing damage in the long run say he makes it to 315K likely it’ll start consuming before then.

Well the Fusion is at 315,000K and the engine doesn't consume oil as you predicted and no sign of engine wear. The engine and trans still perform very well. Still doing 10K OCIs with the engine and 30-35K with the trans.

Good to hear!

As if there was any doubt!

great Mazda. uh i mean Ford.

 

[Sam_Julier]

Well done. You are setting the standard.

 

[tig1]

This Ford is right in line with all the Fords I've owned in the last 50 plus years. Long before Ford bought into Mazda. Some had up to 350K. I drive my cars for years and get all the worth from them I can, as I take good care of them.

I'm biased against ford because I worked as a service advisor in my early 20s during the times of the Ford Windstar, Ford 5.4 3v, explorer etc. And currently my parents own a 2019 edge with the 2.0 EcoBoost which is well known for head gasket and/or block replacement.

I worked in service for years and recognize that they all make some bad ones and Ford definitely makes some good ones but I have always and still do consider them one of the worst brands.

I actually remember the service manager I worked for at the ford dealer when I asked about how the fusions were holding up so good compared to the other cars we were used to...(this was after I was already moved on to work at gm) and he said something along the lines of Mazda is the reason these cars are so much better. Lol.

So your biased. Yes and a friend bought a new diesel Merecedes and the engine failed after 40K because the oil pump failed. Yes some Masada's have failed also because of engine failures. etc.

Yes but it's bias based on first hand experience. Some of every manufacturers vehicles have failed. Especially high end vehicles like Mercedes. But Ford is definitely up there for high numbers of problems and they are commonly bought by people who are financially much more affected by a major failure like transmissions, head gaskets or full engines which ford seems to be very good at messing up. Lol.

A friend of my parents always bought Ford trucks and I made the mistake of saying something somewhat negative about Ford in front of him. It wasn't too long after that his daughter focus lost it's transmission (pretty well near 100% failure rate on those dual clutch transmissions). Ford knew they were no good when they produced them but they decided they could fix them after the fact.

Once again, all manufacturers make some bad ones. But Ford is pretty good at making bad ones.

I seen it and it’s great. It’s great oil but it’s certainly no 10,000 mile oil. No oil is. He is braver than I am for sure. And I have seen the issues it can cause firsthand as a mechanic so I won’t be doing the 10,000 mile thing ever. 5,000 it’s fine for, 7,500 is pushing it 10,000 is just insane.

10k in 6 months is a lot different than 10k in 2-3 years
