Mobil 1 syn 10w-30 good for temps under 20f? Oil pressure gauge question

[talontsiboy24]

My motor is a rebuilt 6bolt with around 32k miles on it..Do u think mobil 1 syn 10w-30 should be fine yr round i was thinkin to go thicker in summer time I wanted to bump it up to 15w-50 mobil 1 syn in summer time at least since i do get on it.

Im running a big 16g with moderate mods for now and the motor is pretty much stock but boost is 22-24psi and the car does see wot here and there and lookin at mobil 1 syn 10w-30 material data safety sheet i dont see anything about zinc or even the word zinc in it isnt that bad? what do u guys think?

As for now though its winter time so i wanna put the best in it for good startups but really good protection as i do like to boost in winter to.

You can use 5w-30 with temps below 32*, but that's as low as you should go ....

Mobil 1 is actually a terrible oil for our cars with its lack of superior wear protection. You can use that weight if youre in colder climates, thinner if extremely cold, but use a Royal Purple, AMSoil, or Brad Penn oil in your car for maximum protection.

Theres been some extensive tests done, and with the Mobil 1 oil, it showed almost immediate wear differences on turbo thrust bearings compared to the other oils i suggested.

ive had my car for 3 years and this is honestly the first time i heard someone say mobil 1 was bad for us, i always thought it was good for us , guess im gonna start reading up on this asap

^^THis. Mobil 1 isn't the best but it's still decent. A 5 or 0 grade of Rotella is very good, weather is be the synthetic or not. Data that I have seen from a test shows it has more ppm of zinc, and molybdenum then even Amsoil, and Motul. Those are important for cold start-ups. A thinner viscosity at colder temperatures is also important which is why I say go with a 0 or 5 grade synthetic oil.

Any motor oil you can get off the shelf for your car will be close to the same viscosity at operating temperature. Just focus on the thickness of the oil at start-up. That is where a lot of wear comes from.

Sorry but this is BS, theirs alot more to it than that, besides It's not the Brand... Mobile One

it's ALL GF-4 oils EPA mandated ZDDP (the main anti-ware additive) to less then 800ppm years ago

We all just when over this in another thread when someone posted the PDF above help-save-your-journal-bearing-turbos

To the OP Don't run a 5w-30 oil like said above unless it Never gets above freazing...
Also Mobile One 15w-50 would be the best when it's not extremely cold out...

 

[GsXdSmKingGsX]

Royal Purple has done the trick for me!

I dont care whats "supposed" to be in it, factual evidence proves it to be inferior.

I was only stating mobil 1 being crap, because it was mentioned. Try not to take offense too much.

But if were going off words alone, youre wrong, brad penn 20w50 would be the BEST, not Mobil 1 15w50

 

[MY1GDSM]

You are wrong, Read the link x98awd posted. Thats where i got the information from originally. I dont care whats supposed to be in it, factual evidence proves it to be inferior.

As a matter of fact, I have, Like I said there's more to it then "All mobile One Oil's are crap" Read the Thread I linked the 2nd page start to get in-detail abit more about what is going on... .

Im aware, hence why i edited the part to tell you to read it. Link me to the part youre telling me to read.


My main point that i would like to make. Brad Penn is > all. I dont want to go into it much more because were getting off topic from the OP original post very quickly.

Also, ill just toss this out there too, Royal Purple > Mobil one .

 

[DSM1G90]

Kinda of a no-brainer with that .pdf report: If you gonna do some heavy racing and/or use a high output turbo usage, you best stick with a racing oil .... duh!

 

[MY1GDSM]

I'm not taking offense

I'm just tired of people Reading that PDF and not fully understanding all of what is going on...

What I'm trying to say is Under that Particular situation more then likely the same thing would have happened with ANY GF-4 oil not just "Mobile One 10w-30"

So comparing oils that have nothing in common is kinda BS. If they would have ran the oil that Mobile One would recommend for that application that wouldn't have happen.

This Has Nothing to do with BRANDS of oil

Who would know the difference though? The manufacturers sure dont explain worth a damn. Example, an EVO oil cap have Mobil 1 Factory Fill actually written on it. Doesnt say "what" Mobil 1, just mobil 1 10w30. Which in this particular case, is the oil im referring to that has proven to suck. Plain jane off the shelf Mobil 1. One would think that it should be the best for that car, when in fact it is not.

It does have something to do with brands, actually. All brad penn has highhh zinc and phosphorus numbers, nearly double compared the rest of the brands out there. Royal Purple also has quite a bit. Again, i was ONLY STATING mobil 1 because IT WAS MENTIONED, im not sure why youre hung up on that, i feel like youre reading much deeper into what im saying, opposed to the simple point im trying to make. Im not saying "mobil 1 is the worst oil out there, and thats it", im just clarifying that to the OP because he, again, had mentioned that brand.

 

[Tyeler18]

I use Castrol Edge 0w-20 in all my DSM's in the winter time. Never had a problem with oil pressure or cold start-ups. Summer time I switch to a 5w-30/10w-30.

He's backing his point, and he's right. Although, shouldn't have said mobil 1 is terrible without explaining.

Please explain why you would only use 5w-30 when it's always freezing?

A 15 grade would be worse to use than a 5 grade for any temperatures he will experience in Illinois.

youre right, my ADD gets in the way here...im thinking a thought and start typing half way through it haha, happens all the time.

 

[joat09]

Are you talking about me, or MY1G?

And youre right, my ADD gets in the way here...im thinking a thought and start typing half way through it haha, happens all the time.

haha yeah. I knew what you meant, and I knew you would get a shitstorm for saying Mobil was terrible.

I would hope that someone that has modified there car to the point that the Car in the test Does...

It doesn't say what Mobile One to add on the oil cap. It doesn't even say 10w-30 but, it does say Fully Synthetic Oil Required

Also FP doesn't say in the test what they used...

What your missing I think (Which it's hard to tell on forums how people are saying things) is that I'm not hung up on what your saying, it's that people read that and are saying don't use mobile one without understanding Completely why when it's not about the brand even if you say it is...

How Fp is going about saying what oils to use
Just doesn't make sense

Sure "Off The Shelf" Mobile One isn't the best choice in a purpose built drag car... but neither is a ton of other brands off the shelf oil... It has to do what's in the oils not the brand sure some of the oils you listed have more ZDDP in SOME of their oils as regular 10w-30 Mobile One
but they also have oils in their line up that meet ILSAC /API specification requirements which mean they have the same amount of ZDDP as any other oil that meets the requirements.

So all in all If say I were to take say

Mobil 1 Racing 4T 10W-40 oil
And turn around and compair it to
Brad Penn Bp-7064 10w-30

The same thing would have happen except it would have been the Penn oil that failed.

Understand my point now?

Please explain why you would only use 5w-30 when it's always freezing?

A 15 grade would be worse to use than a 5 grade for any temperatures he will experience in Illinois.

5w oils are only meant to be used In our Cars when its 32 or below and are too thin to be used any other time.

I guess you probably miss the last part

Also Mobile One 15w-50 would be the best when it's not extremely cold out...

Although I should have probably said Mobil 1 Racing 4T 10W-40 oil would be best considering his location since it stays pretty cold...But considering whats all done to his car (He doesn't have a mod list) I think dispite the lower levels of ZDDP think he will be fine with Mobile one 10w-30 in the winter

Thats pretty much for fp turbos i have a big 16g.

 

[joat09]

15w-30 will not be better than 5w-30 for any temperature in Illinois for his engine. Most of the wear will be at start-up. Both 15w-30 and 5w-30 will have the same viscosity at operating temp.

I wouldn't promote using conventional Mobil 10w-30. There is a lot better for the price. I assume it wouldn't be a huge problem but for a performance application I wouldn't even consider it. The colder temperatures we are getting into are where oil is most important, as well as the dog days and the extreme temps our engines produce.

 

[talontsiboy24]

My motor is pretty much stock with a big 16g so whats wrong with running mobil 1 synthetic yr round? Its not like i have a built motor or mad horsepower though i am pushing 24-22psi on the 16g.

I don't know why anyone would say that M1 synthetic would be wrong to use, but there is just better out there.

Thats false saying to use 5w-30 if its 32f or below im running mobil 1 SYNTHETIC 10w-30 and my car fires right up in even negative temps we see out here in chicago and its synthetic so it flows better the convential and mobil 1 says its good for -20. I still go wot and see high rpms here and there in winter time so 5w-30 would be too thin i think. I ran the same thing in summer mobil 1 synthetic 10w-30 and my turbo is still fine and no issues.

never said 15w30

I said 15w-50 and I was referring to it because of the higher ZDDP content of it...

I also never said "conventional" oil BTW I'm well aware of the how SAE viscosity ratings work... I also said,Because I realized where he was. that Mobil 1 Racing 4T 10W-40 oil would probably be his best bet for maximum protection because of the location.Also IMHO I think that 5w-* oils have no place in our cars and that if you really want the best cold start protection theirs better option out there like This there is also ones that go on the Pan.

Thats false saying to use 5w-30 if its 32f or below

I never said that... . What I meant by that is not to use it above freazing...

Why start a thread asking if your going to make asumtions about what people are telling you
