Oil Recommendation

Nice Breakdown!  I still do think that DI engines are more apt to fuel dilution...I am also taking a BOX of MORTON SALT with Blackstone's Fuel% numbers for a number of reasons.  I have seen your thread on the Cooling/MPG's interesting no doubt.  I was worried when I bought Truck about Cooling issues and how to combat.  I have not seen anything to warrant it though and GM does like these engines on the hotter side.  Plus, adding extra fittings and hoses accessories electrical draw etc.etc. I am already cooking the battery like clockwork every 14-15 months?  

 

My reason for Catch Can install was mainly for fuel dilution.  I am a hardcore BG proponent and keep my DI system "CLEAN" seems to be working?  I will probably never take a 5K sample if I am looking good at 10K+ during winter and Summer?  Blackstone charges extra 7.00-8.00$  for total 38.00$ ish?

 

If I keep trending like I am...I might possibly have a engine outlast a FERD engineered engine?  LOL....god I can't stand FERD! 

Fuel dilution concerns. Test done is a GC. Accurate. Back up is your Flash numbers which for you are very high which isn't possible with fuel in the oil. This is a flash cup test were the sample is heated Sloooooowly and a flame passed each degree F until it goes POOF. I'd say your numbers are on the money friend. Don't look a gift horse in the mouth.

Wix has a oil test kit that cost 10 bucks. Plus postage to send it in. Part number is wix 24077 on rock auto.

 

They use a lab called ALS Tribology . The TBN test is included for the $10 plus postage. 

 

Cheaper than Blackstone

Hopefully, the data quashes those "urban Legends" the whole 0W-20 is strictly CAFE related?  Thanks, for the feedback!   MOOK

If that is the case, then a few companies would need to modify their "claim" that 0-20W is for CAFE on their website ;-)

I said, "strictly" related to CAFE? Meaning it's not the sole purpose?  It provides the best of both worlds in efficiency and protection Hot/Cold it's what the Dr. ordered!

Grumpy Bear, what brand thermostat are you running, I am thinking of switching to a lower thermostat than the 197. Maybe a 185 or 190.

Bottom three or four post give the details for the thermostat. It's a Stant. Reliable as a stone axe. 

I have a post on this page as well with sources, part numbers and so on. This is a post on this page from flyingfool that list some ACDelco stats and an alternative to IPSCO for to hose splice in.

Spertech 5w 30 in el paso heat

[Jacoby]

Im doing an oli change this weekend before I head to the beach with our toy hauler.  Gonna give the Rotella Gas Truck 5w-30 a try.  0W-20 just seems too thin to me in the TX heat.

There is on a rebate on that oil on their website site. I bought four of the 5 quarts jugs of it at Walmart.

Then why does the 2018 owner's manual for the Camaro LT1 engine recommend 0W40 or 5W40, and the 2018 manual for Corvette LT1 recommend 5W30?  Everything that touches oil in these motors is the same as the L86.  The "harsher conditions in a performance car" is total horse crap, as the L86 has to push an additional 2,000lbs at all time and is subject to heavy towing loads as well.  They even recommend 15W50 for track use, so again, the expectation is those oils are for uses less severe than the L86 truck sees.

If you research a little more, there is a tech bulletin out calling for 0w40, Mobil 0w40 esp Dexos 2 to be exact, to be used in the new vetts and back dated for previous years.

Which still isn't 0W20.

 

I run Mobil One 0W40 in our German cars.  Will probably just starting running that in the truck once I'm out of free oil changes; lot easier just having one oil on the shelf.

That should work just fine.  Just wondering how things will be in the long run say, 200k miles running that oil and it's effects on the VVT and cam phasers. 

 

I just ran 0w-20 in my 2002 which calls for 5w-30 and did a UOA and it was just as good if not better than the previous UOA's running a thicker oil.  So to me running a 20w isn't an issue.  This is on a 188k mile vehicle that pulls a 4k lbs trailer for an hour up and down I-40.  Running 2,800 on the RPM for that hour.  Only to keep it from shifting back and forth out of OD.  I understand everyone not liking the 20w oils but to me it isn't an issue.  Especially if you run a quality synthetic like Mobil 1, Redline or AMSOIL.

Again, how would it be okay - per GM's recommendation - on what is a nearly identical engine on the Vette but not on these trucks?  Why would you be concerned about anything in the L86 and not equally in the LT1?
