Ok so my local mazduh dealer wants 175 plus tax to do a compression test. Does or where can i buy a compression tester? A OEM tester is probably some $$$ but geezs thats just the price of a few tests i am sure. Can anyone tell me where to get something that will help me get my #'s. Is there any kits i can buy to save money and give me decent readings or how do you do it with a piston compression tester?

thanks
brian

 

You can use a standard piston tester:
