I am just the opposite. Why spend a few bucks more for something that has no proven benefit?
Does the $29/jug of Mobil 1 EP oil do anything more than the $21.50 jug of Supertech Advanced Synthetic oil in the timeframe/mileage being used? Both are 20,000 mile oils (which almost no one will use for that mileage).
Same for the filter. Is there really a difference in using a basic Supertech filter for $3.50 vs a Fram Synthetic Endurance For $13?
You could go the "expensive" route and spend $42, or the "cheap" route and spend $25, and would bet have the exact same engine life.
$820 in 100,000 miles vs $500 in 100,000 miles if you change the oil every 5,000 miles (probably the median of most here).
Sure it is only $320 more over that mileage, but what did you gain for that $320?
"Peace of mind"?
OK, good for you.
Me personally, I still have a stash of ~$0.50 qt synthetic oil of various weights and manufacturers.
Once that is gone, I will buy the cheapest API rated oil and a Fram orange can or Supertech filter and drive my vehicles, not worrying about the engine life based on what oil I use.
Changing the oil and filter on a regular basis (based on several factors) has more to do with engine life than what oil and filter you use or how much it cost.
