I know there are tons of oil and Walmart threads, but my search did not reveal the info I was looking for, so please bare with me.

After 2 years of being a chicken, I finally decided to change my own oil in my 1999 S420. I paid about $79 to get this special electric pump, ~$12.00 for a filter and about $37 for 8 quarts of Mobil1 0/40W. So, just for oil and filter I paid about $49.00. My Mechanic use to charge me ~$45.00 for an oil change. I just called Walmart and they charge ~$15.00 for the oil & filter change (for 5 quarts) plus another ~$14 for the additonal 3 quarts. That would be about $32 including tax and stuff. Al most a 35% savings. No mess no hassle, & no oil to dispose of. It seems that letting Walmart change my oil is the smart move. Am I missing something?

Thanxxx in advance.
