Everything and I do mean everything else like what's on the shelves at wal-mart is a highly refined conventional basestock. The government allows the definition of the term synthetic used on these oils because of how refined they are. But molecularly the shape isn't uniform or consistent. That's why when switching from conventional to synthetic in older motors they will sometimes start to leak. The perfectly uniformly shaped molecules get by the minor inconsistencies in sealing surfaces but if you switch back the oil stops leaking. So if your paying the same price for mobil 1 as the 3 I mentioned your getting ripped off
Yes you are correct, you've told me several times already
...i've already read BITOG's website.
I choose to use Mobil 1's "Synthetic" for a few reasons...It's readily available and easy to find. You can actually get it fairly cheap if you watch for coupons to advance auto or autozone and stock up. If for some reason, I need a qt, I can have the wife pick it up without her getting confused
In my experience...I switched to it in my 98GT when I bought it at 28K miles, drove it daily in all weather until 110K miles when the intake cracked (common on the 98's - not oil related) and didn't have any problems. It seemed to run smoother, no ticks, no leaks and actually seemed to increase gas mileage a mile or two.
The way I look at it, if my 03 Yamaha R1 racebike with 143hp/74tq dyno'd, spends most of it's life at 10-12K rpm at speed up to 165mph on the racetrack can spend all of it's 40,000 miles on Motul 5100 Synthetic BLEND
15W50 and never leak, never burn and never had any engine problems - never even opened except for valve inspection at 25K...I would say a Mobil 1 "Synthetic" 5W30 oil for my daily driver is just fine.
I think the key with oil regardless of all factors is to use a quality filter and follow a oil change schedule.
Just my $.02
