I will defiantly give it a try, is amsoil even dexos approved ?

Amsoil OE was. I am not sure now. I prefer oils that exceed min standards, re-read my comments a few posts ago about higher end "real" synthetics or advanced base oils formulations. Many exceed standards of API,ILSAC, OEM licensed formulations, which are ALL formulated to a minimum not ball busting better.

Send me a PM on what you are looking at getting and I can get you a quote as well as get you set up as a Preferred Customer where you save 25% over the prices listed on the web site.

 

AMSOIL exceeds the dexos specification.  It's not on GM's list.  AMSOIL isn't going to pay to be put on a list so GM can make more money off them.  The product speaks for it's self.  It is all I use in everything I own that takes a lubricant.  Have been  for over 20 years now.

Amsoil oil will pass Dexos requirements. Dexos is a GM standard that oil companies have to pay GM for that endorsement. Many choose not to pay GM for a Dexos label. 

At least try Amsoil OE oil.

How many times can this be said? 

:idiot:

 

Not ripp'n on you diyer2 but those you and everyone else keeps writing this to. 🥴

I've used Amsoils hydraulic, transmission, and engine oils in extreme conditions. I’ve experienced oil pressure not dropping off in extended usage and even lower coolant temperature under extreme conditions. Using in hydraulics I’ve seen a reduction in pump failure during an hydraulic hose failure. Keeping pumps and motors lubricated during shut down when there’s little oil present. Truck transmission life extended using Amsoil transmission fluid. In the field doubling the hours between oil changes with no effect on longevity. Increasing profits, lowering waste. My experience excludes  hundreds of clearing equipment. Dozens of heavy duty trucks and regular passenger vehicles. Using Amsoil as intended saves money, eliminating waste. I’m an experienced believer.

I run Amsoil Signature Series in every vehicle I own, and my two kid's vehicles.  Nick set me up as a preferred customer and now I just order from the web and it's delivered to me from Arlington, Tx in a couple of days.  Being a preferred member, you can get a case of 0W20 for $142, that's $11.82/quart before shipping and sales/excise taxes.

I can't think of a single reason why 'lifter tick' would happen with one oil and not the other. Both oils are in the same viscosity range and grade. 🤔

 

Unfortunately, some GM engines are known for lifter tick, cam lobe scoring, piston slap, sticking rings, and excessive oil usage, Grump. Our family has been unlucky enough to have 2002 and 2009 Silverados with these problems. On cold startup, until fully warm, they sound like the first 80 seconds of Van Halen's Hot for Teacher song cranked up. Our experience has been that within the same viscosity, and even the same brand and subtype, the noise (and excessive oil usage) can vary from oil batch to batch and oil filter used, all being within GM 'factory spec'.

 

That being said, your mileage and good fortune may vary, apparently depending on if your parts (and lubricants?) were manufactured and assembled on a Monday, Friday, or the day before or after a holiday.

Pretty dark world you live in Bret. 😬

 

Your answer is in the word COLD. What happens to viscosity below 40C. The CCS value has a maximum per SAE grade but not a minimum. 5W* for example has a CCS of 6600 cP at -30C/-22F. It isn't a linear curve. 

 

Mercedes Benz 5W30 is 6,612. 

Valvoline EP 5W30 is 6,200. 

Citgo Supergard 5W30 is 6,100 

Pennzoil Platinum 5W30 is 4,000.

Red Line HP 5W30 is 3,000.

 

Pretty good difference. About the same in cP.

Makes a big difference in cold flow. 

 

I'm using the Valvoline R&P 5W30 in my problem child. Around 6,200 CCS. Sounds like a diesel when it starts cold even when cold is but 20 F. Quite on startup with Kirkland 5W30. 4,400 CCS.

D4684 pumping vis is more critical since modern engines starters and batteries will crank in about any temp. 

 

Gelation D5133  as another.

Here’s a snapshot of Mobil 1 EP 5w30 SM I tested years ago. Any Gel index value above 6 units can be a problem. In other words air is not a good lubricant. I show kinematic vis which is not dynamic for comparison.

Here’s Redline 10w30 SJ tested in 2004. It failed gelation index testing.

Yep. We live out here where, if someone says 40C, everyone blinks, looks at each other, shrugs, and then i Google it later when there's cellphone coverage. 🤷😆

    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
