Gas prices - OUCH!

[cuda hunter]

I've rebuilt four motors due to the AFM systems.   I hate them. 
Sure, if you can go buy a new truck every few years they work great. 
Any AFM system with mileage is just asking to fry some lifters. No longevity.
Or I just have bad luck and  I don't drive like a grandma.

It's interesting you say that. On the new Challenger forum, people are also complaining about lifter failure on the 5.7 and 6.4 Hemi's that have 4 cylinder deactivation. The recommendation there is to always drive in sport mode so the cylinders don't deactivate.

It would be interesting to get some insight from Stellantis engine engineers on the subject.  There could be more to the picture than just the cylinder deactivation feature.
For example, I do know these engines are very sensitive to needing oil changes done on time and proper oil grade used.
Many people don't get their oil changed by the recommended miles. One of the many reasons I do my own oil changes is I don't trust the mechanics or techs, I've even heard of dealers service departments using wrong grade oil in customers cars not just the quick lube joints.  The 6.4 uses 0w 40, not using 0W 40 is asking for trouble and some lazy tech or shop cheaping out on oil might be all it takes to fubar an engine.
This is one of those situations where you need to study warranty data to know for sure, a few random reports doesn't tell much.  Im sure there's cases where oil changes were done on time and correct oil used, and problems still happened. But what is the failure rate in those cases, 1%, 50%? It makes a difference to me deciding whether I should stay in tow haul mode all the time or let cylinder deactivation do it's thing and save me money.
Only warranty data would tell give the true answer.

Mine were all gmc's.  First one failed at 170K.  I rebuilt it stock.  Failed lifter again at 5K.  Oil changed correctly.  Stayed in the deactivation mode.  I was warned to get the module to turn off the cylinder deactivation system.  I didn't get the module.  It failed.

Different engine.  Failed at 80K. I rebuilt stock and installed the module.  It's around 40K now.

I have the first motor that I rebuilt sitting in a garage and I'm going to install the delete kit lifter system so that I don't have to use the module that tricks the computer.

I have a coworker that had his fail at 150k miles.  He used the module to defeat it with the rebuilt engine

From what I have read the earlier models were a bad lifter design or manufacturing process. (Isn't every failure) but the newer are more from oil issues (dirty or wrong oil).  2019 they made another design change To dynamic fuel management (DFM) and now they are back to having lifter design or manufacturing issues at even lower mileage (10k or so)

I plan on keeping mine active at least until the warranty runs out.   I hadn't realized GMC also have a speed governor set to 100 mph either due to tires or driveshaft.  not that I'm doing over 100 on a regular basis but found out the hard way on a pass when some jerk blocking in the fast lane accelerated as I went to go around him on the right.  Hoping  module adjustment will remove that also post warranty.   Final querk is using a K&N air filter can cause module failure or bad readings if the filter has been over sprayed with oil.  gums up the sensors.  Fun times.

I've only been able to get my gm's to go 110 downhill.  All trucks. 
I don't have anything newer than 17.

The 6.2 is no slouch.  420 hp.  460 torque.  0- 60 in under 6 seconds and a 14 second quarter and that's with 4 wheel drive 4 door.  Only downside is the premium gas, but I'm not complaining when the fun factor is times 10.   I understand the dodge trucks are faster but it's the fastest truck I have ever had and I got a relative steal buying a 2018 in November of 2018.   Just before everything went bat shit crazy.

Gas prices have started to go back down here in the Raleigh, NC area.   Regular 87 can now be found for as low as $4.29 while most are in the $4.39-$4.49 range.    Sheetz is advertising a huge price drop for the 4th holiday.   Their "88 octane" 15% ethanol gas is now at $3.99 and will remain that until July 5;th as a promotion.

PS...my older V6 Sebring runs just fine on the 88 gas.

yep, coming down here in Houston also. It is $4.29 (regular) at Exxon and $4.23 at Kroger grocery store.
By the time the gas tax holiday happens it might be cheap!

Filled up at noon yesterday for $1.979/L $215.00 CDN....Went back the the same gas station five hours later $1.949/L  Went back today at Noon....$2.049/L Ten cents/L difference in one day is crazy...

[cuda hunter]

Middle of Colorado just went up 10 cents.

[anlauto]

Our Government lifted one of the taxes so it's supposed to drop 11 cents or so tonight, July 1st

After a lot of thinking...im convinced the prices we pay for gas, food, housing, clothing, etc is governed by one simple thing....GREED.   Or said differently its "just because they can" !

Want an example?   Back in 2015 my wife's Kia Sedona mini van, brakes started pulsing badly.   Turns out the a caliper had gone bad, and caused the drivers side rotor to warp from the heat.   So, i bought a rebuilt caliper, new pads, and brought the rotors to O'Reilleys to have them cut.   Price...was $11 a rotor.   Not bad.

Ok my 2008 Sebring Convertible has had the brakes pulsing for over a year, and i finally decided to have them fixed.   So, in the morning i called O'Reilleys to ask if they could cut the rotors that day...they said sure...   so then i asked what they charge expecting the price to go to maybe $15 because of inflation.   Their response was $25 a rotor...   i said you mean for a pair?  NO, they said per rotor...   so that is about 150% increase in 8 years.    This isnt on something which is labor intensive, or consumes a lot of materials...it is simply for a service, in which they place the rotor in the machine and turn it on and it automatically adjusts and runs about 15 mins to perform its function of truing the rotor.   WHY...BECAUSE THEY CAN...after all the prices are going up on just about everything, so we need to more than double the cost of this service !!!   

Well...i told them..thanks but no thanks, and bought new Raybestos brand rotors from Rock Auto for $27 each...just $2 more than the cutting service !!!  Oh and at Oreillys the price of new ceramic brake pads would have been $52 for a set plus tax...so there 2 cuts and pads would have been $104 pls $8 tax for $112.   At Rock Auto new ceramic pads and two rotors with tax and shipping came to $92.   Thank you Rock Auto !!!

This morning in Houston, at Costco! Just a $1.00 lower and we're back to "normal".

[JH27N0B]

I'd love to see some $4 gas here.  Maybe our Costcos areunder $5 but everything in my area is still well over $5.  I got gas for $5.15 over the weekend but most stations were about $5.50.
