Just changed the oil on my 98 half ton 2wd 5.7 liter. Did everything normal and started it up and there is a code now. Engine runs fine. Have not went over to auto zone to have them read it yet. Figure it just read the oil pressure as low when i started it??? Anybody have similar experiences???

code just went away when i drove home from work today so i figure it was just the new oil working its way through the engine for the first time and set off the oil pressure guage. btw i switched from castrol syntec to valvoline and it is much quieter and the slight leaks stopped!!!

Even if the code went away it's still stored in memory...If your Curious.

 

It could be anything, like an EGR code or O2 sensor on its way out, and just happened to manifest at the same time you chanced your oil.

Pull the codes. Might have been something important. And, as Draenor would probably agree, Amsoil would be much better than the Valvoline.... :seeya:

Sorry... Amsoil is no better than Valvoline synthetic. That is a crazy claim. Both are EXCELLENT products and Valvoline full synth has been getting rave test results. (just like Amsoil does)

Its all good...Pretty much comes down to preference and whatever gives YOU a warm fuzzy feeling. I like RP, its done me no wrong. Even the additives in Dino have gotten better, if you change it every 3K or so....your golden whatever you use, as long as its a decant company...and a new filter every time.

 

I know I don't have to do it every 3K with synth, but I get the stuff for less than the average person pays for a quart of Dino anyway. :dunno::lol:

 

But lets not turn this into an oil brand bickering thread.....we have enough of those already. :D:D

In 1999 the National Advertising Division (NAD) of the council of Better Business Bureau ruled in a debate of what is "synthetic". Mobil challenged Castrol's replacement of polyalphaolefins (PAO's) with hydroisomerized waxes in their synthetic formulations. The Bureau ruled in Castrols favor and allowed them to call this hydroisomerized processed petroleum oil a synthetic. The NAD ruled that synthetic was just a marketing term since there was no true definition of what synthetic is. Since then many oil companies have replaced their True Synthetics with this highly refined petroleum oil in place of the more expensive True Synthetic PAO's. These new highly refined petroleum oils are better in quality and performance than the cheaper refined oils, but only come close in some parameters to a True synthetic oil but are cheaper to manufacture.

 

Companies like Amsoil, Royal Purple, Red Line etc continue to market true synthetics, all the oil company brands are the highly refined petroleum described above.

Wow, all that is awesome. I was just messing around. Sure, I sell Amsoil, and I think its great oil or I wouldn't sell it. I could rattle off all kinds of stuff that says its better, But if you keep fairly clean oil in your engine, no matter what brand, you're not going to have an oil related failure.

 

And, back to the original post, pull the codes, might be something important. :lol:

FWIW the synthetics that come from Dino are so highly modified they really don't contain any dino anymore anyway. Also FWIW if I could find that Shell Rotella synthetic oil in 5-30 i would be all over that. I use the 5-40 in my motorcycle and it performs better than the stuff specifically made for cycles. :lol:

      Gas Prices

      By Chuck FB · Posted

      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.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
