Mobil 1 0w30 or 5w30

Schredder · Apr 7, 2011

Greetings,

Question relates to 2010 Chevy Equinox with 2.4 ecotec. After the factory fill, the car was always received Mobil 1 5w30. I chose Mobil 1 5w30 due its HTO6 designation thinking this approval should help reduce any intake valve deposits associated with DI engines.

I know that Mobil 1 0w30 does not have the HTO6 designation, but I gotta think that this weight should due well in the 'nox. I have also read on here, that the 0w30 is the better oil of the two.

Thoughts?

Chris

I'd run the 0w30 over the plain vanilla Mobil 1 5w30 all day long. Their Mobil 1 Extended Performance, Mobil 1 Truck and SUV, and Mobil 1 High Mileage 5w30 oils are better than the regular 5w30 Mobil 1, in my opinion.

I like the "plain vanilla" Mobil 1 5w30 and there are trade offs with the Mobil 1 Extended Performance, Mobil 1 Truck and SUV, and Mobil 1 High Mileage versions that I don't like.

The AFE 0w30 is Mobil 1's lightest 30wt oil.
Whether it will produce lower intake deposits over the heavier 5w30 I can't say, but I would not think so.
BTW, at the present time only the 5w30 oil has the GM dexos1 designation.

*Correction* The Mobil 1 Extended Performance 5w30 now has Dexos Cert as well. The new SN bottles coming out have the green Dexos label on the front. EP is the best oil Mobil 1 sells according to the Mobil 1 site.

Btw- just wondering what tradeoffs you do not like. I run the HM and EP's and they perform very well so far.

Yeah I was wondering that too.

They're all heavier and have a lower VI's, particularly the HM.
If you plan on a very long OCI then OK to the EP.
If you want the seal swell then try the HM.
But if you just want a heavier longer life oil then blend in some Mobil 1 0W-40 instead. A 50/50 blend will give you an as thick as the HM but with a much higher VI of 176 vs only 162 for HM.
Otherwise stick with the regular 5w30.

quietriot · Apr 7, 2011

I realize the post is about 30, but ive ran both Mobil 1 5w20 and 0w20, to tell a difference mpg etc, id have to flip a coin.

CATERHAM i'm running ESP 5w30 in a few engines any issues with this oil.It sure has the specs.

I like the higher HTHS of the 5w30 HM and EP above the reg Mobil 1 or 0w30 Mobil 1. If it matters to anyone the Mobil 1 OW-30/40 are not rated for ACEA A5, which means the oil is not as stable for long drains. Since I run 10k plus OCI's in TX heat, I prefer the higher HTHS and the stability of the A5.

To answer the OP, any of these oils will get the job done and make the engine outlast as long as he/she will probably own the car.

used oil analysis have shown that Mobil 1 0w30 and 0-20 hold up well for 10K OCIs in most engines even though they are A1. Mobil 1 0w40 is very suitable for long OCIs. My daughters MB calls for 13K OCI with Mobil 1 0w40.

The latest version of Mobil 1 5W-20 is a much thicker oil to the prior version with it's HTHS vis of 2.77cP; if you likely you can think of it as a HM 20wt.
The Mobil 1 0W-20 is as light as it's ever been with it's HTHS vis of 2.6cP which is typical for the grade.

This oil is similar to Castrol's GC, even a bit heavier.
In fact it is as close to being a 40wt oil without being one as you can get.
What I don't like about this oil is the same as the other Mobil 1 5w30 variants; it's lowish VI of 164.
If you want a heavy 30wt oil you don't have to settle for a low VI, thick start-up oil. Simply blend Mobil 1's excellent 0W-40 with either their 0w30 or regular 5w30. For example, a 3 to 1 blend of 0W-40 and 0w30 will give the same HTHS vis as ESP but with a VI over 180. What that means is that the blend will be lighter at all temps below 60C and almost 20% so at 0C.

That's why I don't like these lowish VI Mobil 1 oils; their are much better options available.

I like the Mobil 1 0w20/30 a lot. They still have not updated the PDS to reflect GF-5/SN.

As DI engines are pretty hard on oil, I'm wondering if the 0W oils are a bit thin for that type engine.

The one consistent thing I've noticed with DI engines is that oils with little to no viscosity modifiers do best staying in grade, which is to be expected. Some VM's are also better than others. That is the only thing I have noticed. Redline is a good example, and so is Amsoil ACD/DEO Mobil 1 Turbo Diesel Truck.

CATERHAM · Apr 8, 2011

The main problem with fuel dilution is not the oil thinning out per se but the cylinder washing; hence the high iron in UOA.

buster · Apr 9, 2011

True. It does seem to destroy the VM in some oils.

In terms of engine noise/responsiveness in the Honda, the Mobil 1 0w20 SN oil is the best to date. I would assume the Honda/Toyota 0w20's would be similar based on their viscosity specs. The Mobil 1 would handle high temperatures a lot better.

CATERHAM · Apr 10, 2011

There is nothing lighter at typical start-up temp's than the so called "ultra low viscosity, high VI" 0W-20's from Honda, Toyota, ENEOS and CAM II. With their 200 plus VI's they are in a league of their own.
For example, Mobil 1 0W-20 is 20% heavier at room temperature and over 30% at 0C than the EOM made Toyota Brand 0W-20 and that's comparing virgin oils. The Toyota oil shears also immediately (by design) about 10% once put into service making it even lighter still.
