    I save the gaskets for other things.
    Spin ons were the best invention for autos.
    I remember the old style filters.
    I once had to put 80-90 in the crankcase in an emergency to get home.
    Drained it and put 30wt in and all was good.
    Dont recommend this though. Good vid.

    Sorry Scotty, I have to disagree with you on one thing. The oil viscosity. At least in certain circumstances it can be better to choose one grade higher of viscosity oil. If it is summer and you live in the south, or somewhere else where it gets above 90 degrees, then you should at least look at your owner's manual and check to see if it recommends using a higher viscosity oil during the summer. I have had cars that specify certain viscosities for certain temperatures but the oil cap only specified the general purpose viscosity. I also believe that this is the reason my car started burning oil after one extremely hot summer vacation trip through California and Arizona. If I had used the thicker oil that it called for, it would probably have ran another 50,000 miles or more before it started to burn oil(almost 200,000 on it now). It was actually quite noticeable of a change. It was all fine and dandy when I did my pre-trip inspection, and through California, and then after traveling most of the way through Arizona I noticed that it was starting to smoke a tiny bit in my rearview mirror. I still kick myself for not thinking of it when I changed the oil to get ready for the trip.

    Another thing about oil viscosity is that manufacturers have to reccomend the correct weight of oil for all possible driving conditions (and crazy drivers), but if you know that you will never redline your engine, or even come close, and you are more likely to lug your engine, then it would probably be better to use one grade higher of viscosity.

    Here's a tip…. Never change your muffler bearings while the engine is hot because you will get burned !…always use a sky hook to hold up the muffler while you change the bearings.
