GREAT NEWS!!

Thanks, Mark! And I'm about at the right mileage to switch. And I won't have to use OW-20.

 

Thanks Mark!

 

Thanks for the info!

 

Sweet. This will become readily available at auto parts stores.... not just order right?

 

Thanks for posting!

 

Cool!

Now only if Wally-World (AKA WALMART) will stock the stuff in the 5 Qt jug I'll be a happy camper... I have not checked yet, but In suspect the oil capacity is 6.0 US quarts? no?...

 

When switching to Mobil 1, at what mileage should it be done? And why not when the engine is new?

Just wondering because the C4 Vettes with LT1/4's came factory filled with Mobil 1.

 

TacoBill,

The decision on when to use a synthetic debate is at best described as a very personnal issue... You'll rarely get the same answer twice... now that you've "popped the cork" let the discussion rage...

I personnally don't see a problem switching over after initial break -in ... say 3000 Miles...

I have run Mobil 1 15W-30 (or a sythetic blend on occasion) in my 89 5.0 for the last 10 years... No problems... I also run Mobil 1 15W-50 in my 03 Buell XB9S and have done so since after the 500 mile break-in (I also run it in the primary)... I got 10K on the Buell works better-n-new...

There are many opinions on when to switch to a full synthetic.

I read this article, Oil as well as listening to others who have made the switch at ~10K. Some may agree, other may not. I have ~7K on my Mach, and will use Dino-Oil 1-2 more times and then switch.

On my last two cars, I switched to Mobil 1 at the first oil change (approx. 1,000-2,000 miles). The Mazda only has 17K on it but the my previous (Acura Integra) had around 50K on it when I sold it. Haven't had a problem with either switching that soon.

 

Great Link Oh Evil One!

 

Thanks! Glad you thought the article was informative. The author seems to know his stuff.

 

With more manufacterers going to 5W20 its about time it became available

 

And now its time for Costco to get it!

 

Awesome Mark!

That one issue (lack of Mobil 1 5W-20) has been bugging me big-time ever since I found out that 5W-20 is the recommended oil. Now I can sleep peacefully, and dream of the day my order finally arrives at the dealer. B)

 

now this is good news
i will switch to mobile 1
I hate giving money to amsoil

 

Well that article was a great read, but now I'm confused. I was planning on putting Mobil 1 in at 3k miles, but after reading that article I am not sure about that now. He states that 10-12k is a good point to start using full synthetics, before that the engine hasn't fully broken in yet.

Course I just bought 35 dollars worth of Mobil 1 yesterday too, bleh.

 

I'm not one to quote from magazines. However, if you ever look at performance results during their 'Long Term' tests, most autos seem to pick up performance ~10-12K. In some cases as much as .2-.4 tenths in 0-60, and 1/4 miles times. Which would leave me to believe that the engine is in fact broken in around that mileage.

But as with most other things . . you can take that with a grain of salt.

 

I just bought 2 cases of 0-20w, I was under the impression this was fine for the new stang, what gives? any info?usable?
