Most reliable engine, independent of oil used?

[windnsea00]

BMW I4 and I6 engines seem to never really die if maintained, they just slowly loose power after an absurd amount of miles. Also they can take a beating throughout their whole lifetime which is impressive IMO.

A lot of the BMW/MBZ/Volvo engines of the 80's and early 90's seemed to really go for the long haul, especially the diesels.

Toyota F series (as used in the FJ40, FJ45, FJ55 etc) pushrod engines

 

[Anduril]

Ford Duratec 3.0 (Ranger and Taurus) should make the list as well. Not powerful by any means, but it keeps going and going.

I think you mean the Vulcan 3.0 litre. My vote is for the GM 4.3 and ford lima 2.3/2.5.

 

[Kestas]

I've heard many people refer to the Chrysler Slant 6 as the best engine.

I've had the following engines that qualify. Olds 350 v-8, GM 3.8 v-6, Ford 300 I-6, Honda 110 ATV 3 wheeler (tried to blow this one and couldn't), Briggs & Stratton 3.5, 8, 10 and 12.5 HP engines. I also had a Datsun 210 (not B210) that was great but I can't remember the engine size...was a I-4

Usually oil is not the determining factor on engine life unless the oil is Amsoil used by Amsoil dealers.

 

[tangojetta]

The Ford 3.0 24V Duratec motor is pretty good motor.

Toyota 22r/re
Toyota 4.5L inline 6 (from landcruisers)
GM/Ford/Dodge slant/inline 6's
BMW inline 6's

For the most part, inline 6's...just based on my own experience, not scientific.

I knew my gm 3800v6 was a good engine but this Good?? wow i'm impressed and very happy with my choice!!

 

[Spitty]

I don't think Wards criteria considers long life and reliability regardless of oil used. Hey, a few years back they even had the Northstar on their list!

 

[obbop]

All things being equal..... whatever THAT term really means...

Wouldn't a lower compression engine lend itself to a longer life, assuming equivelent maintenance, lack of casting flaws, proper air filtration system in place and a few other etceteras that don't immediately wnvelope my fragile thought process?

 

[ThirdeYe]

Forgot another one, the Nissan VG30DE/TT. Such an amazing engine, used in the Nissan 300ZX (and a few other various Nissans outside of the U.S.).

model t ford , beetle flat for and ford l head 8s only outstanding quality was their siplicity and cheapness to repair. None of those engines could be called reliable by modern standards. Nostalgia aint what it used to be.

my vote for reliable is the 2.7l I 6 in my 88 528e. The car has never failed to get me home under its own power. 342 k miles and counting

 

[windnsea00]

^The E28 engines were very robust, the M30 I6 are known to take up to 30 lbs. of boost with stock bottom ends!

 

[Brogy]

Just like spitty said, those are more of engines that were the best for their time, doesnt mean they're the most reliable.

In that case, just about every engine mentioned so far is probably less reliable than many engines coming in '07/'08 vehicles.

Everyone has mentioned engines within their short life of driving vehicles, but do you really think most of those are more reliable than a new engine in 2007? I doubt it.

In order to name reliable engines, you have to look at their contemporaries.

1989-1990 Chevy 5.7 V8in the pickups. The ones with the simple injection system. I have seen 3 go 350,000 mile + in company trucks without a lot of help in the maintence department.
