The Pureone is one of the best out there. I don't think that's overkill. Overkill would be a K&N every 1500 miles or something.

i guess youre righty, but still it's nice, shiny, and blue, ohhh ahhh.



at strauss auto they have cutaways of "leading brand" "purolator" and "PUREONE", basically pureone looks like it has 10x as many pleats/folds as the purolator, which itelf has 10 times the folds/pleats of "leading brand".



which leaves the questions if purolator is so good, why is it's competitor the "leading" brand? hehe, i asked an employee that question and he was lost.

Castrol 20-50.. but that's just me, i ALSO use a purolator "BLUE TIN" oil filter



When scott over at mazsport use to change my oil he'd use Castrol 20-50 and an OEM mazda filter. That's just as good

"GOod luck, let us know" CHEERS!

Go buy a magnetic drain plug. They run about $2.00 at autozone. Nice to have. A little extra help for the filter. Also, good way to moniter for trouble.



James

you're oil pan should have a magnet in it already, at least i know a bunch of cars have one in there maybe not the rx7.



if youre going to get a new drain plug go for the ones that dont need to be removed to change the oil, makes it super quick https://www.nopistons.com/forums/pub...IR#>/smile.png

haha, good question

Isn't it 6.1 quarts? The Haynes manual says 5, the owner's manual and FSM say 6.1 US quarts. Just changed it for the first time on my '88 vert and added 6 quarts.

My old '79 took 5 1/2 quarts.



Filter is easy to change being on the top just poke a hole in it as it drains and put a rag underneath as Rob stated. I like to turn the left wheel to the right, can get to the plug without jacking up car. It's a 19MM socket.

its 5 quarts, I dont know where you got the extra oil to go?

Is the FSM and owner's manual wrong? I was a little suspicous when I saw the Haynes said 5. I changed the filter also of course if that adds to the capacity.



If it's 5 I guess I now have an extra quart in there, should I drain it?

The owners manuel says to put more oil in the car than is needed. Thats why you check it every time you pour a quart in.
