I'm thinking of Mobil drive clean or chevron
what do you think??
What's the best 5-30 dino for winter?

Pennzoil seems to have the best cold temp properties among conventionals. I would go with chevron before mobil driveclean.
Nothing wrong with Chevron Supreme
What kind of car/engine will you be running this in?
Frankly, I've been impressed with most of the UOAs turned in with the 5w-20 oils. The Motorcraft/Conoco synblend seems to be the best. If you change every 3000 and you have a tight tolerance engine these might be the ticket. ![[I dont know]](/forums/graemlins/dunno.gif)

It's a 2.0L DOHC ZETEC in a FOrd ZX2. I've always changed oil 3000 to 3500 miles. I never thought of 5-20W. I know ford now recomends this oil in my engine. When I bought the car it said 5-30W

Last year's Chevron book shows 5W20 and 5W30 supreme with a pour point of -45F, and 10w30 at -36F.
The 5W30 synthetic at -62F, and 0W30 Delo at -76F, with the 5W40 Delo at -45F.
PC's Duron 5W40 is a little lower at -54F.
At those temperatures....I'm stayin' inside.
This new 5W-20 is insane! EPA ratings are what this is all about. I mean what about when the engine gets hot, don't you want some viscosity then? What are you in the arctic circle?

Being new to this site doesn't mean I'm sitting on my shoulders!
Many of these "studies" are commisioned by mfg. companies and not to be trusted. At least you're smart enough not be using this nonsense yourself.
I'm of the opinion that even 5W-30 is an attempt to impress the EPA regulators. And that in the vast majority of cases is NOT what people should run "all season" as suggested by certain auto makers. ![[No no]](/forums/graemlins/nono.gif)

Motorcraft 5w-20 synblend UOA in a Ford V-10
then decide if they are BS or not.
Try to find a crappy UOA on these. It may be counterintuitive but they are producing solid reports.
When Ford speced 5w-20, they doubled the requirements from their previous 5w-30 tests. It was like a 60 hr stress test at some unreal temps, which was pushed to 120 hrs. My F150 was speced and filled with 5w-20, but as many people here think, I'm still unwilling to fill my crankcase with anything thinner than a 5w-30.
Don't bash it though. If a V-10 can get exeptional UOAs with it, towing no less, I think we all have something to learn.
Between the two you mention, I'd take the Chevron.
I've lost interest in Pour Point as a useful indicator of cold weather performance.
In order to qualify as a 5w, the oil must pass a Cold Crank Simulator Test at -30F and a Borderline Pumping Test at -35F. Period.
Notice that even with a pour point of -27 F, the Chevron still carries the same 5w rating, meaning it still passes those tests.
Now, Pennzoils numbers in passing those tests may be better, but the Chevron still passes.
Anyways, reality is that 99% of people will never see temps that cold anyways. I know we see them here in Minnesota, but then I still use Havoline 5w20 (which provided the quietest start I can remember at -13 F last week).
Mobil Drive Clean is a good oil also. I've used it with all my vehicles, and have never had a problem with it. Wal-mart carries it for $1.00
a quart, and sometimes you see it on sale at Target, K-mart, etc. I have used several name brand oils over the years, and have never had a problem with any of them. Chevron Supreme is also a good oil, but isn't carried in some of the same stores that carry most other brands. The most important thing IMO, is to change your oil regularly.
