2019 Sierra and Silverado Motor Oil Weight Change ???

[Black02Silverado]

Considering the new 3.0 Duramax takes a Dexos2 0w-20 oil that dealers can purchase now tells me that the 0w-20 in the gas engines is here to stay.

Interesting for sure.  

Thanks for the info newdude!

But if someone was to engineer and sell a dipstick retrofit kit,  I'll bet many kits would be sold. This is a real opportunity for some adventurous soul.

I saw one of those videos, too, and it looked like a fairly straightforward bit of engineering to fit something into that check port (where a dipstick tube could go).

 

I am currently driving a 2010 5.7L Tundra and plan to trade it in on 2 019 Silverado or Sierra, soon as they arrive for test drive comparisons.

I hate not being able to check the transmission fluid on the Tundra, and intend to attempt to devise some easy way to check the fluid on the 10-speed transmission behind the 6.2L engine while I wait for that retrofit kit.

 

Hello to all from Bremerton, Washington.

Welcome!

 

How’s the Tundra been treating you?

 

You’ll appreciate the mpg gain, interior layout and options on GM Trucks vs the Tundra. I’ve heard good things about the Tundra, mostly reliability.

Thanks.

In 156,000 miles, no troubles at all. Fresh fluids on schedule, replaced serpentine and brake pads at 95,000 and spark plugs at 120,000.

What I'll miss most is the 46 gallon fuel tank I had TransferFlow install back in 2013. I don't tow, but being able to drive all day (700+ miles) on the freeway without worrying about fuel stops is great.

Also, the Tundra is stiffly sprung, so I hope these new 2019 GM pickups ride a bit smoother.

I'll likely get one regardless. My wife and I are recently retired and able to travel, and one of the new GM pickups is what we wish to travel in.

A little concerned about this stop/start thing and the DFM. I know the stop/start can be switched off, but I hope the DFM can be as well.

DFM won’t be able to be turned off without a tune. Current AFM can be disabled temporarily by shifting into M5 or M7 depending on 6 or 8 speed transmission. 

 

I hope GM offers a larger fuel tank. It’s been the standard 26 gallon tank since 1988!

 

GM has had a 36 gallon on HD Diesels since 2011 with the 6.6’ bed. You would think they could offer something larger on half ton trucks.

Seems needless engine mechanical complexity for what appears, from my initial research, to be minimal gains, and hoping the DFM can be disabled by some means so I won't have to experience those things I read being caused by AFM. Understand DFM is mechanically not as complex as AFM and may be a bit more robust, but I'd rather it not be an issue at all.

Fuel tank size is ridiculously small considering many people will want to tow with their half-ton. Already looking at replacement options for a gasoline tank for late model GM pickups and finding nothing. Diesels have a large selection of replacement tanks, and I wonder about the possibility (and legality) of converting a diesel tank to gasoline to give extended range. The 46-gallon tank for my Tundra was the best $1200 I've ever spent, for the peace-of -mind I get from not having to plan a highway trip around a fuel stop every few hours. That 46-gallon tank of ethanol-free gas will easily get me from Seattle to Sacramento. I hope to be able to find something similar for the GM truck I want to buy.

I did a search and see this discussion on fuel tanks.  I'm in the market for a 2019 truck.  I currently have a F150 that has a 36 gallon tank and having a decent sized tank is important to me for the range it provides.  I like the new Silvy and Sierra and the 6.2L option, but what is the story with fuel tank sizes on the half ton?  I'd want a crew cab/short bed.  Thanks

I can't be the only one that finds a 0w20 in a diesel spooky...I thought 10w30 (6.7 powerstroke) and 5w30 (2.8 duramax and the cruze 2.0/1.6) was spooky seeing the bigger engines ran 15w40 but 0w20?

An update.  Not sure if the oil cap deal was an experimental thing, but so far GM has confirmed 0w20 weight for the L84 5.3 and the L87 6.2.  Both engines obviously being the new DFM equipped engines.  Now, it is possible that it may or may not be a typo, but that's what they are showing. 

Based on youtube videos of the first trucks hitting the lots, it is 0W-20 for the new trucks at least the 5.3 & 6.2.

My 2019 Silverado with 6.2L burns a quart of oil every two thousand miles. At first the dealership said that was excessive. Now they say its normal. I can't get to a 5000 mile oil change without adding 2 more quarts of oil at 4000 miles. Normal????
