That is exactly what it states.

That's not what I said, that's not my logic, that's what the professionals at Car and Driver said. I am quoting; not making a statement and you can bet I will take their word, their lab reports, and their test results with calibrated instrumentation over your "Feeling" any day without hesitation.

You can run 87 octane all you want. I don't care if you use diesel or what you do. I've made my point, which is validated on scientific evidence, certified test results as reported by professionals within the industry.

Prove it. Car and Driver did and made a statement to the fact.

I'm outta here; this is a ridiculous argument of evidence and fact against hearsay and baseless perception.
It`s only designed for premium if it states;(premium unleaded fuel only)as per my 1987 Mercedes 300E stated.

Hey, CK1, when I want to know something about International Whifflebells, I always consult the truck driver who delivered them. Those guys always know everything about what they're tooling around the country. LOL. My '02 RX runs just fine on regular. It would run just fine on premium. It is not the couple of extra bucks premium costs me that bothers me, it is the many, many, extra bucks the industry gleans from we the people. I always used premium in my '97 Jag Vanden Plas 'cause Jag told me to in no uncertain terms. That engine may be the best 6 cylinder ever manufactured. We had other issues with the car (paint, headliner, mounts & bushings), but we spent zero dollars and zero cents in 7 years and 72K miles on the engine. Sort of reminded me of the old Dodge & Plymouth sixes from the early 60's. Oh, yeah, I'm no spring chicken. Enjoy your day, guys.
