Fact.....half a bottle of Slick50 Synthetic does improve greatly cold weather starts.

 

We just had a below freezing night. Not snake oil.

I don't even notice a difference in starting until approaching zero?

I didn't notice a difference until the 20's

We've had several nights below freezing and my 5.3 with original factory oil, I  only have 4500 miles on it, starts fine but the rods rattle for a second or two.

 

I might ask the dealer if they'll put in 5W and if so get the first free change early.

 

After reading the above link is it possible the extended crank times were intentional for oil pressure to rise and since it does not list 2017's maybe they took it out.

 

Are they talking fuel pump or oil pump, not really too clear.

Wasn't Slick 50 sued and pulled from the market a few years back for being snake oil?

I wouldn't run it...if it was so great, the big oil companies would buy it to use the formula.

How will a higher viscosity oil help with oil reaching rotating parts quicker in cold weather?

Hoping there will be a film left from shutdown from Dexos1 5w30

On my 2007 Silverado with the older engine I noticed no difference between 0w20 and 5w30 but this is a different beast.

It's the high pressure fuel pump. There are two fuel pumps. A low pressure electrical pump in the fuel tank and a high pressure mechanical pump that sits in the valley of the engine (driven off a lobe on the camshaft).

The pickup pump sends it to the charge pump needs extremely high pressure and probably 40 and below ALL GM DI engines will operate in this manner of longer crank times to reach pressure.....The DI's are a different animal that is for sure!  Mine has 44k plus and unbelievably strong I have no doubt these engines are far and away a cut above any small block GM has done extremely impressed...oh. and 20.5 mpgs right now?  Sick, couldn't pay me to spool up a 2.7 and call this acceptable?

No, they lost their rear honoring their engine warranty...which they stopped in 2013....GM axed it's powertrain warranty in 2016..  you will be SOL if your motor croaks at 60,500 miles now. ..

 

It's amazing how less amps and torture on the battery is needed to start this truck in below freezing weather....with just a half bottle of Slick50 Synthetic

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Blazer is all put back together. Another hard-won battle. The 4.3 is not easy to work on in such an archaic and narrow chassis originally designed for an inline 4.   My baffle issue is solved. I returned to the OG junkyard but was ready for a fight. The Blazer I had picked from was stacked on another vehicle so I had no idea how the heck I was going to get myself to working height to pull the front end apart. I had seen an S10 pickup on the ground so I was hoping the part would be the same, AND, I couldn't remember if the S10 still had a front end or not. But I didn't need to worry because it turned out to be my lucky day. The yard had just taken in a '98 Blazer, sitting right up front, on the ground, with room to work around it, and the front end hadn't been hit. The baffle and all the clips were factory perfect. I also scored another good handful of odds/ends and the whole shebang only cost me $20.   Got everything back together and it fired right off, sounds good, runs good. I've got a little coolant drip from a lower water pump bolt (D'OH!!). I did the right thing and snugged it down a little bit, and of course that didn't fix it. Yet again, I will have to soak everything in coolant to drain it down to the water pump, remove the bolt, and attempt to re-seal it. Nothing is easy on this truck. Nothing. But now all the radiator plastics are correct, snug, and fully functional. No more rubbing on the cooling fan. It runs, drives (took it for a 30 mile drive last night), no Check Engine lights, EGR is working, no vacuum leaks. We're getting closer...   The replacement wiper motor arrived yesterday. The tailgate was already disassembled and waiting, so I threw that in. It works! Sort of. Two new issues on the list. While the motor is strong enough and the gears aren't stripped, the wiper is hanging up on the bottom of the rear glass. This is the old style where the lower half folds down like a truck tailgate, and the glass swings up, and they meet in the middle when closed. The glass isn't sitting flush with the tailgate, now that I look at it. No rubber bumpers that I can see for adjusting, so I'll have to look at the hinge adjustment to see if I can correct it. Also, the washer/squirter just dumps fluid underneath the truck. The lines actually run inside on the floor so I'm guessing the tailgate is soaked at the rear trim and the line is disconnected. There's also a drain there....probably for this reason.   The leaky water pump bolt was really disappointing. JUST STOP LEAKING...OMG!!   Replacing the window motor and a rear door speaker are still to do, and then everything will work. I want this to feel like a "good" vehicle worthy of dropping $600 for new tires before I do. That means no leaking first. I hurt, and I'm kind of cranky, so I'll probably take a day of rest and do the water pump again tomorrow.

      Just saw on Jay Leno the new Scout. That’s the way it should be done.

      EV's have their nuances too. Best to operate the current type of lithium batteries between 20-80% charge. No real need to charge until you hit around 20%. Occasionally charge to 100% when needed. Longer term storage, battery should be 50-60%. At least those are the guidelines for our iX. We've been exceptionally good to the battery in that car...easy to do when you can charge at home like we can.   EV's lack so many of the rituals and so much of the visceral feeling ICE vehicles provide, which is why I think they're hard to accept for a lot of gearheads. They're fun in different ways, though.

      Winter Returned

      We have got a lot of rain lately, we needed it. Storms/lightning took out a floor fan. Dirt roads badly rutted from run off.   Power here is sketchy, whole house surge protector in the service panel and all electronics plugged into surge protectors. My biggest concern is my stereo, I've been an audio nut for years. $25 k in equipment. Stereo is on it's own special surge protector.

      Happy Birthday!  I also turned 72 this year.  In some groups I consider myself to be a young senior and in others I realize I have serious years behind me!  In June I spent a week in the hospital due to a blood clot following knee replacement surgery.  The hospital Doctor assigned to my care specialized in Geriatric medicine!  He is a great Doctor but the fact I required this type of specialized care  made me feel old!  Aging comes with new challenges but I sure appreciate getting older!  It most definitely beats the alternative!!
