      Chemical synthesis is simply using chemistry to make a different molecule.

      So here is a question.

      Synthetic oils use components (molecules) that are chemically synthesized. There seems to be no doubt about this.

      What about regular mineral oils? Are the molecules of this product chemically altered or are they just somehow taken from the crude oil without any alteration? Because if there is chemical alteration or synthesis, then these too are synthetic oils.

      And all the synthetic versus mineral just might be advertizing.

      Funny world we live in.

        If two oil of the same viscosity grade, synthetic or not, have passed all the API testing protocols……

        ……then engine to engine differences are much greater than oil to oil differences.

        There is little hope of ever matching the best oil to a particular engine. Fortunately these oils are very versatile and will would quite well under the great majority of circumstances.

        Change oil at least yearly, change filters every two or three years, keep the oil level within specification. Not more difficult than that, IMHO.

            Valves are really pretty easy to adjust if you have one of two things. Engine knowledge or an exact procedure to follow that substitutes for knowledge. But an Accord V6 is probably not a great place to begin learning unless you have a tutor present.

            I don’t know if you can use Eric’s site to locate a subscriber near you who might be a tutor for half a day. My friends generally know that I’ll “bust hump” on their cars with them present to help if they buy me lunch. It’s a depression so “Will Work for Food”

                Get the valves adjusted. You don’t want to drive too much with that clatter.

                Piston slap really happens under engine load, not at idle.

                    Eric:

                    Agreed that was an informative video.

                    Do you have an opinion why cat-converters go bad? Bad fuel. Wear out? Overcooked?

                        Sounds semi regular. Is a half broken timing belt slapping around?

                            I’ve never had an NGK fail. Wear out yes,but never a misfire due to bad plug.

                            Had a tour of a Champion factory years ago and we demonstrated how they used high voltage to test plug quality on the manufacturing line. Every one failed, but he put them back in the line.

                            Poor luck with Bosch too.

                                Thanks guys. I have determined that lifting the car rolls the jack in and lowering pushes the jack back about 5 inches.

                                This means that the jack’s wheels should really be able to roll on a clean smooth floor.

                                I guess it also means that the jack should not be elevated with blocks of wood under it but rather on the lifting pad.

                                More later……
