Internal combustion engines of today can routinely give 200,000 plus miles of trouble free service. Many of us remember when reaching 100,000 miles was a rare accomplishment, so don't confuse a high mileage engine (compared to historical mileages) with using some "miracle" oil that dramatically reduced or eliminated wear.
Reading your owner's manual and using any oil, changed at correct intervals, that is recommended for your engine will provide you with economical long term, high mileage service from your engine.
I have to agree with this quote.
I'm sure the Purple and Mobile 1 are great oil but any oil will work as well if changed regularly. I've used Valvoline in everything I've owned since new and never had an oil related issue.
