#485 of 717 Shared 3.6 engine in lowlife Pontiac!!!!
Apr 10, 2012 (12:11 pm)
Yesterday, I made a bid on a used 2008 Pontiac G6 GXP w/16k mi to a dealer in central Florida.. I see it uses the same 3.6 engine as the base Model CTS..The G6 Pontiac is no dream, but the GXP is equipped nicely with leather, sunroof, and other goodies..My bid was safe and their asking price was way too high, and they countered, but still way off..They have my number if they decide to get serious..After reading all the complaints on this forum, the base 3.6 power is not worth the risk..Having owned 53 cars to date including 3 Caddies, all new and driven by wife mainly except for the 15 round trips from Michigan to S. Florida, I would not spend any money on a new one. The engines in mine were 1-4.9 and 2-Northstars. The 4.9 was replaced by Cadillac 59k and car was sold 150 miles later..The Northstars were okay..
Mobil oil seems to not last in the Aluminum Blocked V-6s or 8s, so I switched to Pennzoil on the Nothstars and the Olds engine V-6 called the Shortstar..3-4k before down a pint..
Currently I use "Royal Purple" in my Supercharged Pontiac GT and is changed every 6k..Hate to part with the car for I bought it 1/2 price in 2007 w/4300 mi.. 2006 model. Had a tranny oil cooler installed for the Florida heat destroys the transmissions. The interstates in the South are great places to roar and the tranny temps ramp up quick..At 70k miles showing it has been cheap fun, only gone thru 5 batteries, 3 steering shafts, and main engine and tranny mounts..
The old iron-block 3.8 V-6 sure isn't high-tech but it doesn,t mind being pushed..Never complains..
Good luck-Caddy fans

If you're buying GM I think it's best to stick with the old tech OHV engines (i.e. 3.1, 3.4, 3.5, 3.8, or 3.9 liter engines). The gasket problems are easily recognizable and can be remedied by the updated gaskets. These engines are generally good for 150 to 200k miles without any other major problems. The 3.6 seems to be good for about 50 to 75k miles and then all the troubles start. Good luck.

I agree and have had the a few of iron blocked V-6s, 2-2.8, 1-3.1, and 6-3.8 with the current being the 260 hp S/C 3.8..Had 2-3.5s, the dual overhead cam, alum block V-6 used solely in Olds Intrigues 1999-2002 and the Olds Aurora..Both Intrigues were loaded GLS models, 1999 went 75k miles and traded on a 2002 Intrigue which did 120k miles..Both cars had only one modification, catback exhaust system by SLP..Zero engine problems, the 2002 had a spark plug change 110k..The 3.5 alum engine had a 6.5qt oil pan capacity..
Not a Caddy fan, but my wife liked them, so one knows the rest of the story..She was a great gal..My son has had 7 Caddys, last one was a 2002 STS which suffered a cracked block around 170k, and was quickly traded in on a new 2008 300C Chrysler Hemi..

Hi Sara I just got my car back today 4-12-12 from the Kuhio Motors service very disappointed,I pick it up for the oil consumption test after 1000miles but I went over 380 more miles couldn't find the right time to bring it in,for that 1380 miles on my 2010 cts consumed 3/8 of a Quart. almost a qt, the dealer said it was normal for the 2010 to 2012 to consume a quart every 1000 miles. till it breaks in.?????.so I ask myself when will it break in and when will it stop eating oil.I thought only older cars with high mileage consume a lot of oil.I bought this car for reliability and its the other way around. problematic but to the dealer nothing is wrong.So they top it off again and said they will monitor it again for another 1000 miles.I told the mechanics why did you top it off again?no ans. should just left it till 3000miles .just bring it back after 1000miles and monitor. I'm sick and tired of this run around.#808639-1679 vin A0105493 DEALERSHIP KUHIO Motors

I'm sorry that you're so frustrated at this point. I am going to ask our Technical Assistance Center about the approved oil consumption rate for the 2010 CTS. Once I hear back from them, I'll have a better idea of how to proceed from here!

Hello again ceto,
I heard back from our Technical Assistance Center, and they stated that the accepted rate of oil consumption for 2012 and prior vehicles would be 0.946 liter (1 qt) in 3200 km (1988.387 mi).
If we can set up a Service Request for you, please send an email to socialmediagm.com with the following information:
your name and Edmunds username
phone and address
the last 8 of your VIN and current mileage
the name of your dealership and description(s) of any recent visit(s) you have made there on this issue
I realize you posted some of this information here, but as my coworker Christina answers inbound emails it helps to have all of the information in one place for her.
Thank you for your patience as we work through this with you,
GM Customer Service

How about GM tells its customers why there is any oil consumption to start with? How about GM warns its customers on the front end before their $55K Cadillac is a P.O.S. that no body will touch? Is it the synthetic oil? Is it the model of motor? I don't know about you, Sarah, but many of us have driven GM (and other brands) for decades that never, never consumed oil. If there was any oil consumption you couldn't measure it on the dip stick. The oil would eventually break down or become loaded with deposits and not lubricate adequately, but you didn't lose oil unless you leaked it or burned it. It has been a long standing fact that the crank case would stay full of oil until you changed it at 5000 or even 10000 miles. What is going on? Why is no one at GM addressing the underlying issue of consumption? This 3.6L V6 should come with a warning to check the oil every 100 miles. At least that would be "up front" about it instead of letting the customer fine out the hard way. It's a curious way to build brand loyalty. Unless, of course, that is not part of the marketing strategy. Puzzling, me thinks.

The alum blocked ones I owned were all somewhat on the thirsty side for oil consumption.. The Northstars weren't too bad but the Shortstar, the Olds version was thristy..however it had a 6.5 capacity..Qt every 1500 was normal, however on the last Olds Intrigue 2002, I stopped using Mobil and went Pennzoil..went to a qt every 3k, Both Olds Intrigues were driven 90% of the time a high freeway speeds...
