eacall0986,

I normally use Mobil 1 10W40 high mileage, but decided to switch to Mobil 1 15W50.

I can purchase both at Walmart for about $25.00 in a 5 quart jug.

I wish Mobil 1 would offer its extended (good for up to 15,000 miles) oil in either the 10W40 or 15W50 weight.

Since my 99 Boxster has over 233000 miles, if the engine goes bad I'll just part it out and move up to that 996 I been wanting since day one.

Just my two-cents.
