Oil Change

Seriously? If so, what do you drive?
Seriously. I hardly ever get an oil change. I've done this with every vehicle I've owned.

91 GMC Sonoma 2.8l died in a wreck in 95 with over 100k.
93 S-10 Blazer 4.3l died in a wreck in 2006 with over 200k.
98 Dakota 2.5l traded in 2005 running great with over 130k.
99 Silverado 5.3l sitting dead at house with fuel injection issues @ 180k miles
01 Lumina 3.1l running like a champ just shy of 130k on it

Those were the long term vehicles. I've had a few more that I've owned for only a short amount of time. I've never had a problem related to engine lubricants.
