I have used 0W-30 in my S-10 Blazer with no problems, I didn’t notice much of anything. I tend to think lighter oils really only benefit in the winter when it’s cold. However, when I put 0w-30 in my lawn mower, it sounded like the RPM’s were higher. One thing is for sure, a light oil will make any leaks worse so be prepared to be replacing gaskets.

When an engine gets over 100K miles, I don’t recommend using a very light oil because as the clearances increase from wear, there will be much less oil available to the last few bearings which will cause early failure.

IMHO, you should change your oil every 2500-3000 with a recommended or even slightly heavier oil if you plan to keep your car for a long time regardless of cost. But if you just want the gas mileage and you can afford to replace every couple of years, go with the super light weights.

The real answer to extending time between oil changes is to have your oil spectroscopically analyzed. I use Blackstone for this service on almost every oil change. The data they give allows you to make the most of your oil change intervals, and we routinely get the full 10-15,000 miles from a fillup of Mobil 1 EP with a clean analysis report. Some of our cars dirty up the oil faster than others. The BMW 325 yields the cleanest reports and we’re running semi-synth to 9,000 miles. The Chevys are happy at about 12-15,000 miles with the M1 EP. Oil analysis is the only way to know how many miles you can go between changes and it allows you to get optimum life from the oil & filter, thus conserving the resource. Besides, you can “see” what’s going on in your engine, and we’ve literally saved 2 of them by knowing this info.

I like synthetics for the very same reason that vz893 does, I have to change it less often. Considering the packaging (a lot of green where it used to be blue), it sounds like it’s just a branding strategy to seem more green.

Since most people don’t own their wehicles for 150,000 miles, cost savings at the 50,000 mile mark is much more relevent. According to Mobil 1, by using the 0w20/0w30 fe oils, at 50,000 miles, you will save $147. With a 5 quart jug costing about $25 at Wal-mart, doing an oil change every 7,500 miles, the new oil adds up to be $175 over 50,000 miles. With the money saved on gas by using the new fe oil, the cost of Mobil 1 0w20/0w30 oil over 50,000 will only be $28. I like using full synthetic oil for the protection and not having to change the oil every 3,000 miles, so the money saved on gas is just a bonus. Just my take on it.

Will it be worth the increased price tag if the claims are true? That’s the tougher question. Mobil gains nothing by saving you from buying their gas. They gain everything with good marketing though. If this wasn’t making them more money, the finance guys would’ve never let it out.
