10 Car Engines That'll Last Forever!

Reliability means everything in 2024! Today we are opening the hood and looking at the 10 most reliable V6 engines ever built! These engines have been overshadowed by screaming V8’s and big ole V12s but the truth is V6 are the engines we see in most vehicles and with tighter emission standards we don’t see that changing anytime soon!
V6s give off great power while also achieving higher fuel efficiency than the traditional v8s or v12s. It’s also more affordable to produce these engines which makes Dave Ramsey fans go coco for coco puffs for these!
Today, there are loads of modern V6 engines to choose from but some are money pits as they will bankrupt you with maintenance and repair bills! To save you and your pocketbook from generational doom, let us reveal the ten most reliable V6 engines ever made!

My 2003 Toyota 4Runner with 4.0 V6 has 250, 000 miles on it and uses no oil. I have always changed it at 5, 000 miles and have used Mobil 1 synthetic since the beginning. This has been the best vehicle I have owned.

2011 4Runner I gave a Grandson at over 200, 000 miles and now has 350, 000 miles. He recently towed the largest U Haul trailer loaded over 2, 000 miles. Still does not need added oil between changes. Mobil 1 synthetic 0W-20 is the only oil it has had. The engine still runs flawlessly.

My 2010 Toyota Venza has the 3.5L 268HP version of the 2GR-FE engine. It has been rock solid with absolutely NO issues. It is sitting around the neighborhood of 200, 000 miles right now and ticks along as well as it did when new. It worked so well I passed it on to my daughter when she had her first child.

I have a buddy with a 2002 4Runner with 350k miles and it still runs strong. He has, of course, kept the maintenance up.

I bought a 2008 Honda Ridgeline with the 3.5L J-series engine new in Nov 2007, and it now has 493, 000 miles on it with zero major engine (or transmission) problems. It’s had an alternator and a power steering pump and several timing belt/water pump replacements as prescribed at every 110, 000 miles (okay, maybe I cheated a little and went 120K or so), and a few valve adjustments. ALL maintenance performed as per the Maintenance Minder and no sooner. Still runs strong, quiet, and smooth. Uses no oil between changes but does have a very minor oil leak (rear main seal I think).

2002 Tacoma extended cab TRD 3.4 V6. 400k and I just sold it. Still doesn't burn oil. Original except for a radiator, u joints, brakes. Otherwise, all original including alternator and starter. So many miles I went through 5 windshields. Sold it to a hippie at a NorCal commune. It's going to work the farm. Best 23.5k I ever spent .

2003 Toyota 4Runner 4.0 V6 348, 000 miles and still going strong!

[VampirusX]

The Lexus 3.5l used in some hybrid models is bullet proof and need to be on this list!
Just make a list only for Toyota/Lexus. There are so many good V6.

My wife and I own two Hondas, both with the V6 engines and have NEVER had any engine problems. Bought the Accord in '08 and the Ridgeline in 2015

I owned 1990 Toyota 4Runner for 24 years. Never has engine or transmission problems. Odometer showed 424768 when I give her to my father in-law. He had it for 6 years drive only 4432 miles . The car rusted all over the bodywork. And engine was running good and quiet . That was 3.0 L v6 .

2012 Tacoma 1GR-FE here. 225, 000 miles and going strong!

[davidwright]

My 2007 Toyota 4Runner with the same engine has 226, 000 miles on it now. I change the Mobil 1 synthetic every 7, 500 miles. It does not use any oil between changes. This is by far the best car I have ever owned. I am 81 now, and will do whatever it needs to keep it running for the rest of my driving life. I get about 18 miles to the gallon with it, and average about 7, 500 miles per year. Maybe 10 more years of driving before my sons take the keys away...

[stevensheegog]

My 2GRFE A 3.5 L 6 cylinder engine in my old 2007 Toyota lasted 431, 998 miles before it was rear ended and totaled. My transmission lasted that long too.

Now I have a 2018 Avalon with a 2GRFE 3 3.5L 6 cyn engine.

[jamesdonald]

What about a straight six Mercedes W124 E320?? Reliable as hell - still going strong over 30 years on!!!

[oz]

2009 Toyota Fj Criser 4.0 V6 200, 005 miles and runs like the day it left the dealer.

[johnware]

My experience with General Motors 3.8L is spot on. I bought a car just for the engine.

[PAA]

I bought a Mitsubishi Mirage Sedan 1996, 2.8ltr DOHC, 24valve V6, 1 one owner, 59k miles in 2008.
It now has 314.298k. 28 years and still going strong!

[lynfordrhooms]

I drive a 2006 Hinda Pilot EXL which has over 254 000 miles on it. It is a daily driver and still runs and feels like new. It also has the J35A9 Engine...it's bullet proof...I will be driving it until it stops.

I kinda spit up a little when they named the 3.5 Ford Ecoboost and the GM 3800. I worked at a Ford dealer and can't even begin to tell you how many Ecoboost engines needed to be replaced in the F150 and the Edge/Exporer. I would never own one of those. Also, I ran a used car lot. the first Series I GM 3800 was absolutely the bomb, no douht. The series II and series III were practically basket cases. Gaskets, intake plenums, lower engine noise. They only seemed good because they were OK until they weren't but they lived off the reputation of the series I. The Toyota 4.0 and 3.5, yea, those engines take severe abuse. like knocking your coolant hose off while screwing around off road without a skid plate and driving 3 miles to the gas station to buy coolant. or my wife's Lexus blowing an oil return line and laying down oil for a mile, shutting down in my driveway, replace the line, fill and 100K miles later it is still going approaching 240K.
