I changed my oil and strainer and filter all at once, bought a torque wrence and when putting it all back I was TOO AFRAID to tighten it to specs put just used what common sense I hoped I had to tighten it to what I thought was as tight as I needed it to be. Scared the hell out of me to use the full torque specs so did not do that. It was up on stands and had room to work under the car, actually took a few days to tighten it, come back hours later check it again and then the next 1-2 days kept checking how tight it was. FINALLY after days decided it was tight enough and to leave it alone. When I was all done I realized that since the strainer was so clean it was a not needed thing to do anyway.
