Last , oh what was it June?, I needed to do an oil change.
Went to the local discount/drug/department store and "regular" oil was going for something like $2.85 to $3.29 a quart. YIKES!
But they had some "high-mileage" Quaker State or Pennzoil or Valvoline, honestly don't remember, but it was one of the big names -- on sale for something like $1.85 a quart.
The rig is an '87 Corolla with something like 280K on it. It had been using about a quart or so every 1.5 to two months. So, went with the hi-mile stuff, purely on price.
Well, drained that out in the fall and replaced with regular Havoline. The Havoline was replaced with regular Quaker State the first of January.
The point is that the car is not using oil anymore....Never really believed in that hi-mile stuff....and still would not pay a great premium for it, but if the price is comparable, I'll buy it again.
As I said, I only used it once in three oil changes and it seems to have done the job for me.
