Doesn't it just make you want to punch them in the face? Well, if it's your brother maybe...........has less than 3,000 miles on a Jiffy Lube oil change that is going on 1.5 years (can you say, short trips?). His GMC Jimmy has had an external coolent leak since a remanufactured motor was installed from the intake gasket failing and killing the motor (4.3L), coolent filled the motor to the brim. He has a stupid #@$%! K&N intake kit; the #@$%! filter constantly falls off the end of the tube etc. etc. etc., tires are always at about 20 psi. I've offered to change the oil and do a full look over for, you know, a couple beers (free!) or something and he just blows it off.
OH WELL!!
PENNY WISE POUND FOOLISH (although some of you would call me that since I'm a cheapskate with oil/filters/fluids in general but I change them and maintain my vehicle!)
