Any chance at Warren 0w30?

[Rhymingmechanic]

If you want a 0w30, Mobil 1 AFE is readily available. Has a nice low Noack of 8.7% too.

AFE 0w-30 is $24.97 in my area. The M1 rebates will bring it below $15 per jug.

It sounds like the Supertech HM is working for you though, especially if it stopped oil consumption.

 

[Zee09]

Yes, at nearly double the cost.

Mobil users for the most part get it at half the price using the rebates.
It is often rebated and instantly mentioned here.
I'd stay with what you are using-it works great doesn't it?

2020 Silverado 5.3 and 6.2 engines. 0W20

If your vehicle is “loving” the 5w30 then why change? You won’t know the difference and neither will your engine.

I was thinking 5w30 in the summer and 0w30 in the winter. Yes I know a 5W can work well down to very cold temps, it's just an OCD thing maybe.

I believe there is about a 5 degree difference between the two. It depends on the brand.

Once you get that cold anyway it is prudent to take other measures and don’t depend on the oil alone.

My 2020 RAM Hemi 5.7L uses 5W-20, it's on the 710 cap and it's the only grade recommended in the owners manual.

Yes, though you are safe to use a 0w-20 in it. I recall a few years back Mobil indicating that their AFE 0w-20/0w-30 were suitable for use anywhere a 5w-20/5w-30 was called for.

 

[nascarnation]

Honestly 0w20 ST and 5w30 ST would be good enough for 2 cars calling for Xw20 weights

Agree or same thing with Costco Kirkland. If you change twice a year, tailor the blend to the temps. IE if you have a 5 quart sump, in winter use 3 qt 0w20 and 2 qt 5W30. Then vice versa in summer.

Yeah, I know, I was just pointing out that RAM doesn't specifically recommend/require 0W-20 and it's not mentioned in the manual.

The RAM manual it's not what I think of when I see RTFM

 

[Red Crow]

You really never know what the independents may roll out. I'd doubt Walmart or Costco order a 0w30, but perhaps Warren Distribution would market some under the Mag1 brand. I was surprised to hear Walmart started offering Supertech motorcycle oil though, so who knows what may be in the pipeline.

 

[Snagglefoot]

Why 5w takes you to -39 F. You expecting a cold winter?

There is definitely a trend to go to 0w. GM suggests 0w30 at temps lower than -20 F on their new 6.6 liter gas engine.

 

[buster]

Knowing that the Noack of the AFE 0w30 is 8.7%, I'd consider using it. The downside is the potential viscosity loss due to the VII's.

 

[Blinker]

There is definitely a trend to go to 0w. GM suggests 0w30 at temps lower than -20 F on their new 6.6 liter gas engine.

GM has suggested 0W-30 for those temps for nearly 2 decades now.

 

[SwampSurvivor]

As far as supertech branded oils, they seem to only be produced in the primary recommended grade of most lower cost vehicles out there. Not the alternative viscosity recommendation.

 

[Snagglefoot]

GM has suggested 0W-30 for those temps for nearly 2 decades now.

Yes, as a matter of fact, here it is in a model year 2000 Silverado owners manual in the written section near the bottom.

 

[Tomat]

Yes, at nearly double the cost.

With rebate from Mobil 1 price very close to supertech Full synthetic oil

Where can I find these noack figures? Mobil's website doesn't seem to have them. Thank you.

 

[Dennywires]

Maybe it's in my head that all new oil for new cars is 0w based stuff.

You said it’s a 15 yr old van

 

[2EHA]

the 5w30 warren specials are cheap bare minimum oils. a 0w30 wouldn’t be able to use bottom of the barrel base and consequently less profitable. the 0w20s are actually good for some odd reason
