Why would it matter when car is at operating temp. it is a 30 you don't drive around with a cold engine temp.

 

According to the Mobil 1 tech rep, that information is wrong. The 5W-30 pour point is actually 5 degrees lower that that of 10W-30. The important thing though, is that 5W-30 is thinner at normal startup temps, reducing wear that inherent to the startup process.

 

5w-30...just because I change my oil like my undershorts...not because it needs it, but it is a good escape from the wife and kids

plus..it's what the build specs say goes in it...

I'm sorry but somebody at the dealer is being quite dramatic.
Most 5w20 oils have a 100°C, cSt of around 10. 5W20 oils come in around 8.5 if a 1.5 viscosity difference is going to do damage to an engine, it is a very very fragile engine.

 

Pour point doesn't mean much though, the proper number to look at is the cold cranking viscosity of the two oils. And you can see when you look at those specs, that a 5w30 will have much better cold cranking numbers than a 10w30. Pour point is simply 5 degrees higher than the temperature at which the oil turns into a solid. And it's basically a meaningless test.

 

I couldn't decide so I use 3 quarts of each to total about 6. I save the 5-30 for precharging the filter. Oh well.

 

Question;
Where can I find the following items please.
1. Baldwin Oil Filter
2. German Castrol Syntec Oil

Thanks guys.

 

well, it is a Ford engine

 

German Castrol Syntec 0w30 is only sold in the US at larger Autozone stores. Nobody else has it. In Canada it can be found at Walmart, Canadian Tire and Partsource.

I have no idea where to get a Baldwin filter from, but I'm sure someone on here must know.

 

Since the Baldwin is fairly hard to find and the K&N flows and filters just as well, I'd get the K&N filter instead. I've been using one for the past four months and am very happy with its ability to quiet the inherent valve tappping at startup.

 

As a note for those looking for Baldwin filters, Baldwin is the manufacturer of the AMSOIL SDF Oil Filter which can be bought via the AMSOIL link to the left, the link in my signature, or using this info:

AMSOIL Ordering Information
AMSOIL Preferred Customer Program

As a note, the AMSOIL SDF Filters and the Baldwin filters are not the same. The AMSOIL SDF Filter has a special Cellulose, Synthetic and Glass Blend Media. Part number for the C5/Z06 is SDF32.

All sales via my dealership benefit my race team and this site. Thanks for your support.

 

i think you'll see that the Baldwin B31 has a bit more DP compaired to the K&N HP1007..... i.e., the K&N usually has an oil pressure about 2-4#'s higher at idle (that's according to my notes anyway)....... I use the K&N BTW (from Auto Zone)

 

Not that I know what the "correct" answer is here... and actually there probably isn't one, but to add a little info to the discussion.

0w oil isn't by definition any "thinner" than 5w oil, it just has a lower pour point. You can see from the below tables that AMSOIL Series 2000 0w30 actually has a higher viscosity at both 40C and 100C than does Mobil 1 5w30.

Any 30 weight oil will have a cST viscosity somewhere in the range of 9.30-12.49 at 100C (212F).

Almost every oil manufacturer reports viscosity at 40C (104F) and 100C (212F). I compiled the below info directly off the manufacturer's websites. I can provide links if anyone wants them.

First is listing of highest to lowest Viscosity (cST) at 212F or near normal operating temp. Higher is nearer 40 weight, lower nearer 20 weight, all are within the 30 weight band of 9.3-12.49:
Viscosity 40C (104F) cST/Viscosity 100C (212F) cST
AMSOIL SAE 10w30 66.1 11.8
AMSOIL SAE 5w30 64.3 11.6
AMSOIL Series 2000 0w30 56.9 11.2
Redline 5w30 67 10.9
Redline 10w30 70 10.7
Castrol Syntec 10w30 59.6 10.1
Mobil 1 10w30 62 10.0
Mobil 1 5w30 56 10.0
Castrol Syntec 5w30 58.2 9.7

Second is listing of lowest to highest viscosity (cST) at 104F or nearer startup temp:

Viscosity 40C (104F) cST/Viscosity 100C (212F) cST
Mobil 1 5w30 56 10.0
AMSOIL Series 2000 0w30 56.9 11.2
Castrol Syntec 5w30 58.2 9.7
Castrol Syntec 10w30 59.6 10.1
Mobil 1 10w30 62 10.0
AMSOIL SAE 5w30 64.3 11.6
AMSOIL SAE 10w30 66.1 11.8
Redline 5w30 67 10.9
Redline 10w30 70 10.7

I've listed the highest to lowest at 212F as most people seem to want a higher viscosity at normal operating temp, and lowest to highest at 40C as most seem to want a lower viscosity at startup.

P.S. I'm not sure if the Castrol numbers apply to the "German" Castrol. These numbers are pulled off the Castrol North America website for Castrol Syntec sold in North America, which the "German" Castrol is. Best I could do, sorry.

 

I located my Baldwin oil filters by clicking on their web site. Just type in Baldwin oil filter on your search. Once you find their web site you should be able to type in your zip code and find the dealers near you. They will most likely be tractor or industrial equipment distributors.

I am definitely changing to 10w30 oil the next time I change the oil as I still have the tap tap in my '02 vert which has only 9000 miles on it even with the Baldwin filter. I live on the Gulf Coast and I never drive my car if the temperature is below 40 degrees. I store my car in my basement garage which never gets colder than 60 degrees even if outside temp gets down in the twenties.

 

ive been trained by mobil an do preventive ****. for living, in all ive learned. you do more wear in just reving up your car at red lite ,whats called no loading ,than the diff of 5 or 10 will ever make.

 

I had some of my German Castrol analyzed in it's virgin (unused state) and it gave the following viscosity numbers:

67.6 cst at 40c
12.2 cst at 100c

So it is a very thick 30wt, almost a 40wt oil actually. This is one of the reasons why it performs so well in the LS1, because these engines like the slightly thicker oils like this.

 

In my opinion any engine will "like" very thin oils with great sheer resistance. It just happens that some thicker oils do that better. But that is changing.
