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.

Wow 233k congrats on your '99 impressive! Have to ask the question, any IMS replacements done?
I have a 2001 Boxster S Manual 6 speed with 80K and will need to decide at the time I need a new clutch to have it done or not.

Going to my local Walmart for Mobil 1 as soon as I get a chance. I'm also going to be replacing the transmission fluid. Thinking of using a manual pump from the fill opening to remove the old transmission fluid instead of having to remove the bottom cover and the aluminum brace just to get to the drain. Hopefully I can get it all doing it this way. Advise or thoughts if any?
