dbrowne,
In reference to your post about "One of the folks...some analysis and found (???)...We concluded..."
Please do not take this as a flame or harsh, it is not meant to be. I do not blindly put my trust in a company, that is one reason I like this forum here, but I would give the companies such as Pennzoil, Mobil, etc. a little more credit than maybe we do sometimes.
I believe that the tests and analysis they are doing are vastly superior and with a higher quality knowledge and experience than any we are doing. Not that ours would be of "no" value, but as Bob himself states (and is unfairly criticized by some who do not take the time to read and listen to what he has said himself in refernce to his videos)these are not scientific, just some personal observations.
I know that the bottom line is profit, if you do not have it you do not stay in business. But those who keep delivering QUALITY products earn the reputation and strive to do both: make profits while still delivering state of the art quality products.
Sorry for being so long, but back to your post. Here is my experience: yesterday (6/29/02) I went on a little over a 100 mile trip. We up here in northern Minnesota are having some hot weather (mid 90's and humid), it has been worse I am from Virginia.
My Pontiac Grand Prix LE 3.1 v6(224,000) with 0W30 Mobil 1 Super Syn ran as cool and calm as if it was 50 degrees and April. Not an analysis of any kind but just plain old common sense road experience.
We had a couple of 32 below days past winter and now these temps; I would call that an extreme difference in temperatures for an oil to keep on delivering successfully.
2500 miles on this batch and checked this morning and it is still right on the full mark.
Just my experience with the Mobil 1 0W30 Super Syn.
Thanks to all for your post here, it is a great place to keep coming back to.
Good Day,
Steven
