Cool Dexos. Use full synthetic or blend as substitute?

I have a '14 Limited LTZ w/the 3.6. I've always had the oil changed at my dealership as I've had a free maintenance program. It has ended and I'm in need of an oil change. It is such a hassle to take it into the Chevy dealer for service and there is a Jiffy Lube a block from my office. What are suggestions on taking it into a non-dealer service facility? Full synthetic or a synthetic blend? I've read up on the Dexos issue and found links stating that as long as synthetic is used it will not void the warranty. Is this true? Thanks for any info on the matter.

I'd highly recommend full synthetic. These 3.6l direct-injected engines are known to be very hard on oil. A full synthetic is the best option and make sure you change it every 5k miles (at most). GM even had to modify the oil life monitor algorithm for these engines because they were having timing chain issues with the early 3.6l engine cars (they modified the OLM so that it told you to change the oil sooner than it did originally).

Just my 2 cents....

I would also say full synthetic. Not Jiffy lube or any of those other "quick change" places, I've just had way too many issues with them in the past. That and if you want to use something other than their "house oil" it will be really expensive. Non dealer is ok though. I do it myself as it's really easy.

Agree - best to do it yourself. You pick the oil, you pick the filter and you make sure it's done right. Like @worthirt mentioned, those quick-lube places aren't the best option - stripped oil plugs, crap filters, crap oil in general, etc. It's so easy to change your oil, might as well do it yourself.

My worst one is when one of those places "double gasketed" my oil filter causing a massive leak. Lucky I was able to save the engine. Filters and oil plugs do not need to be very tight if the gasket(s) are good. New ones are really cheap if you need to buy one. Oil filter comes with one, just put a little "clean oil" on it before you screw it on and usually the oil plug doesn't need a new one (they are available at any parts store if needed though).


EDIT: A "double gasket" will not leak until it's under pressure, like after you start the motor.

I'm surprised you had a double gasket incident. I worked at JL for a few years and the pit tech is supposed to hold the filter out from under the car so the bay tech can see the gasket and confirm it's not stuck to the car. Stripping bolts is usually lack of attention from the bay tech. When they pull your VIN on the puter, anything like aluminum pans or differentials are noted along with the torque specs for every bolt they may encounter during the service. It's up to him to call those warning and specs out to the pit tech. A good team is very efficient so observing them in the bay before you walk in the door will show you what kind of experience they have.

They are more expensive than doing it yourself but you get a lot of extras for that higher cost. They grease your zirks, check all of your fluids, tire pressure and tread, inspect struts and shocks for leaks, pull the PCV to make sure it isn't sticking, check air filter, washer fluid, wiper blades, etc. They primarily promote Pennzoil products, which are great, but they also carry Mobil 1 and Amsoil (at least they did when I worked there). It's a lot cheaper to hit Walmart and DIY, about half as much. Five quarts of Mobil 1 synthetic will run about $23 and a good filter $8 to $15 (I really like the K&N Wrench-Off performance filters). If you choose to do it yourself, spend the extra money on a good drain pan. Those cheap $3 plastic pans they sell SUCK. They will buckle when trying to pour the oil out of them and make a huge mess. Also, don't forget a funnel as they make life so much easier.

They grease the zirks? Tell that to my upper ball joints, PO that had the car used one of those places all the time and they didn't do the uppers because they couldn't "see" them while the car was down.

They are supposed to unless a lift is required, which they don't have. The car specs they access on the computer states how many zirks there are. I'm not saying every JL or other quick lube shop has great teams working for them. Any business is only as good and their employees. I worked at a great shop full of gear heads and several of the guys were taking ASAE courses and working at JL part time. We all shared a passion for cars. It's one of the few jobs I had where people actually enjoyed working instead of bitching about everything all of the time. Sometimes I even miss it, even tho the pay wasn't great.

Check their website for feedback and also the BBB. If a location has a history of problems it should be easy to find on the internet.

That would be awesome, I think they have gone downhill lately. I've heard that they started treating the employees worse then before and well work just went downhill as they started cutting corners just to get the "job done" I say worse, because pay was no longer by the hour as it went to "by the job" so to get paid more, the techs started churning out the cars as fast as possible.

The power train warranty requires that Dexos1 certified oil be used. Not all synthetic oil is Dexos1 certified. If you are concerned about the power train warranty (you keep all your oil change receipts, don't you?) - make sure what ever business changes your oil uses Dexos1 certified oil. If plastic bottles are used - check the label.

If I were you I'd stick with full synthetic- use mobil 1 and a good filter and do it yourself. Dexos is a rating that lets it go by the car's OLM....supposedly certified oils are good to at least 10,000 miles but I'd only trust a synthetic to that. Instead of Jiffy Lube, find a Valvoline, Castrol, Pennzoil, or Mobil oil change place if you can't do it yourself.
