Good Morning Everyone:
I have been monitoring this Equinox site, and I am wondering why there seems to be a big issue with the 2010 - 2.4 - four cylinder engine in the Chevrolet Equinox, ----- and there does NOT seem to be an issue with the 2010 - 2.4 - four cylinder Chevrolet LTZ Malibu engine. ------- (I own the Chevrolet Malibu, and it now has 44,000 miles!) ------- Outside of a computer software problem with the engine early in it's life, the vehicle is trouble free.)
I have the dealer change the engine oil & filter every 2,500 miles and since the vehicle was new, I have been using a fuel additive, (upper cylinder lubricant), than was recommended by a friend.
When I first purchased the vehicle I noticed that the engine sounded like a "coffee grinder!" ---- It did not have the smooth sound of a four cylinder Honda Accord at idle. ----- My friend suggested that I use a fuel additive in the gasoline on a regular basis, and after a while the engine became very quiet. ---- I am not here to advertise any product, and I do not want to get into a debate as to the need for these products. I am only sharing some information. ---- The two popular fuel additives that come to mind are "Lucas Upper Cylinder Lubricant" and "Marvel Mystery Oil." ---- (They are safe for Oxygen Sensors & Cat Converters) ----- LUCL is more expensive than MMO, but it does the same job! These products can be purchased at K-Mart, Walmart, Pep Boys. ----- I am NOT telling anyone to use these products, I am only stating that I use one of them, and my engine is quiet, and I DO NOT use any oil between oil and filter changes at 2,500 mile intervals. There are only a few possibilities with regards to the Chevrolet 2.4 engines. ---- 1.) The engines in the Malibu and in the Equinox are NOT the same engine. ---- 2.) My choice to do frequent oil and filter changes has eliminated a potential problem. ---- or ---- 3.) My choice to use an "upper cylinder lubricant" in the fuel at every "fill up" has solved a lubrication problem with this engine.
Again, I am not advocating the use of a fuel additive, and I do not work for or sell these products. I am only sharing information!
NOTE: ---- My selling / servicing dealer DOES NOT KNOW that I am using one of these products in the fuel.
Another line of very good products that could be used are BG / Products. Do a google search and you should be able to find a source for these products in your area. ---- They are NOT sold in auto stores, but rather they are sold at automotive service centers. They are NOT CHEAP! ---- I have use the BG / MOA in the oil of my 2007 V6 Camry since it was new. (It was recommended by the selling dealer because Toyota engines in the past were know for producing sludge!) ---- The vehicle now has 83,000 miles, gets an oil and filter change every 2,500 miles, and uses no oil. ----- (I also use the fuel additive in this vehicle!)
I trust that this information has been helpful!
All the best to everyone!

Hello Dwayn...I have maintained my vehicals the exact same way you do for last 20 plus years. I use lucas fuel additive every 4-5 K miles and chage oil at 3500 mile intervals; oil is real cheap insurance. I just traded my 2010 4cyl Nox for a 2013 3.6 V GMC Terrain and this new truck will get the same lucus fuel treat ment and 3500 mile oil changs. My 2010 Nox never stalled or let me down and any drive line warranty work was always backed up by GM Dealer.

Wasting good oil and having to use a bunch of additives would drive me crazy.
I'm at 186k in my '99 minivan and it's lucky to get the oil changed at the recommended 7,500 mile interval.
Once a year I may throw a bottle of Techron in the gas tank.

Changing oil "more often than necessary," and using high quality oil & fuel additives is very much like taking vitamins for the human body. ----- My doctor told me that I am wasting my money by taking vitamins. ----- I still take a bunch of vitamins everyday with my meals. I have the "blood pressure" of a 21 year old male, and I am NOT 21 years old! ---- I am not on any medication. ------ So you see, it is a personal choice. You either believe in vitamins or you do not believe in them! You either believe in frequent oil and filter changes, and oil & fuel additives, or you don't! ---- It is a "free country" and each of us makes our own decisions. ----- Something is VERY different between my 2.4 four cylinder engine in my 2010 Malibu, and the 2.4 four cylinder engine in the Equinox vehicles that I am reading about on this site. ----- Why don't we have the same problems in the Malibu line of vehicles? ----- What is different about these engines? ------ Why aren't we seeing oil consumption problems in the Malibu line? ---- Why aren't we seeing timing chain issues in the Malibu line? ----- Something is different? ----- Is it the weight of the vehicle? ---- Is it the gear ratio of the drive train? ---- Let's explore this side of the issue!
Best regards to all!

Vitamin pills can be bad for you for sure. (cleveland.com)
It always amused me that the company that makes Amsoil also makes a line of vitamins and supplements.
Per Wikipedia, the '10 Mailbu uses one of these engines:
2.4 L LE5 I4 (gasoline)
2.4 L LE9 I4 (gasoline/E85)
2.4 L LAT I4 (hybrid gasoline)
3.5 L LZ4 V6 (gasoline)
3.5 L LZE V6 (gasoline/E85)
3.6 L LY7 V6 (gasoline)
The '10 Equinox uses one of these:
2.4 L LAF I4
2.4 L LEA I4
3.0 L LF1 or LFW V6
3.6 L LFX V6
The inline 4s may share similarities but they are tweaked for different vehicles. That's before we get into the transmissions they may be connected to, vehicle weight, etc.

So why are the 2.4 LAF and 2.4 LEA Equinox four cylinder engines having problems , and the 2.4 LE5 engine in the Malibu not having problems? ----- What is the difference between the two engines? ------ Are the Equinox engines "carbon producing engines," which locks the rings on the pistons, damages the cylinder walls causing "blow by" and high pressure in the crankcase, and as a result, high oil consumption through PCV system? ---- There are too many vehicles on this site having problems. This is NOT isolated cases! ---- I know that my 2.4 GM engine is a lot quieter now, as opposed to when I took delivery of the vehicle in 2010, by using the fuel additive. ---- But, using a product in the fuel is a "personal choice!" ---- I am only sharing some information and observations. The final decision is in the hands of the vehicle owners. ---- They make their own decisions as to how they are going to spend their hard earned money. ---- I like my four Cylinder Malibu. I think that the engine could use a "little more power," but it is sufficient for the vehicle. --- I do a lot of highway driving and I get at least 30mpg. (What is very interesting is that my 2007 V6 XLE Camry also gets 30mpg on the highway, and it can run rings around the Malibu in terms of acceleration. Both vehicles have a shiftable 6 speed transmission.) --------- Best regards! -------- Dwayne
NOTE: I am not worried about an "overdose of vitamins!" ----- Your body expels excess vitamins everyday!

I am pretty sure the 2010- 2011 Equinox used the LAF. 2012- 2013 use the LEA.

There must be a difference in the engines ---- OR--- the engines are assembled at a different location, with different parts from different vendors! ------ As a group we should investigate this issue, and share the uncovered information on this site. This will help the owners of the Equinox. There is something going on with the Equinox 4 cylinder engines that is NOT happening to the 2.4 Malibu engine. Lets uncover the "Mystery!!! ----- It could be a "group activity!" ----- I feel like I am back in High School! -------- Dwayne

We have Identifix reliability ratings here and it may be helpful to compare the 2010 Malibu with the 2010 Equinox.
The Malibu has minimal engine issues between '06 and '10 while the '10 Equinox stands out for having moderate problems.
"An occasional problem on this vehicle is failure of the Coolant Pump Chain (2.4L Engine)."
