Guys that know me might remember I have a 96 Ram Air T/A that I regularly race...but the principles used are the same on any car. The best way to change oil is to:1)allow the car to run for 5 minutes to warm up, 2) once cool enough to touch, remove the oil filter then the oil plug,3) reinstall the plug don't laugh, we've all done it at least once4) prior to installing the new oil filter, spread a thin coat of oil on the seal with your finger to prevent binding on install and difficulty removing next oil change, 5) fill the new oil filter with fresh oil (this is done to prevent dry-starting your car. Until the oil pressure builds and the empty filter fills with oil, the engine is starved for oil. Prefilling speeds the process and protects from this occurring. Also, it ensures you are adding the correct amount to the car. Granted, this doesn't always work on every car, only vehicles that use a vertical filter. If the filter is installed horizontally, you can't do this.6) Finally, fill with the remaining oil. DO NOT OVER FILL! This can cause alot of problems, more than I will go into here.7) Start the engine. Allow it to warm up for five minutes. Turn off and allow to cool for five minutes.8) ALWAYS check the level when finished. Again, I'm sure more than a few of us put in too much or too little on one occassion, so it's not a bad idea to count the empty quarts and check the level. 9) Double check the plug and filter...if there are no leaks, you done!Using a longer than stock filter isn't a new idea. I learned this trick years ago and have been using it on my T/A since day one. First, it allows me to use the whole quart, instead of having half quarts lying around. The added Synthetic provides a bit more lubricating "insurance" and the added volume helps to dissapate some of the engine heat (the oil acts as a heat sink). Most importantly, I use the larger filter because of the additional surface area the longer filter provides. Poor flow is the biggest killer to an engine. If the filter constricts the free-flow of oil back to the motor at high rpm...your done for. At 8000 rpm, the 2zz motor will not last long if starved for oil. More surface area allows the oil to flow into and out of the filter easier. As for brands....Fram has been tested and shown to be one of the worst filters on the market. I've used the Purolator Pure One for years because of the study...folow the link below:
