Thinking of going full synthetic oil in 2014 Chevy, have 40,000 On it and just recently had oil consumption test done. Dealer tells me it's fine even though it had used a little.

I went full synthetic after the 2 free dealer oil change. It's a only a few dollar difference if you do it yourself so why not go full synthetic.

I'm going to go full synthetic after my free oil changes are done. Protects your engine better for a few more bucks... Well worth the investment in my opinion.

I have 3 trucks and all are on the free oil change but being a tech I know not to.I use mobile 1 with a good filter and have never had problems.The dealer uses shit bulk oil and most don't use a gm parts filter.They use what we call day filters because they are good for just a day.

I went M1 in 1999 and haven’t poured anything else since.  I still change it by the OLM.  Wix, Mobil1, STP,  or the new and improved Fram super duper filters.   No more K&N since they cheapened the design.  Definitely not a AC Delco new style.

Mobil 1 all the way.  Dealer used it on first oil change on my 1995 GMC 350 engine.  I stuck with it and put over 300,000 miles on that truck and it still didn't burn oil.  After dealer free oil changes on my new truck I'll go back to Mobil 1.

So, who makes the AC Delco full synthetic that the dealers are using now? Do you think it is an inferior oil too?

Not sure,but probably somebody like Mobil. I use to work at a Napa auto parts store and valvoline made Napa's oil. Same oil just in a Napa bottle. Even had the same address on back of bottle as valvoline.

Ashland made a lot of Napa oils at one point...

If they meet the Dexos certification, it is a good oil...oils have come a long way, and with the certification process required today...they aren't all that different between brands in regards to performance.

Factory fill on 2017 trucks is full synthetic.

So, who makes the AC Delco/GM oil that is used at dealerships? They have switched to the full synthetic at the dealer I use for service.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
