what do u use to drain the oil?
and how do u change the filter?
Topsider brand oil extractor.
Effectively, there is no other way to change the 4C filter than from below, but on my Audi, the oil filter is one of the most easily accessible parts in the engine! Open the hood and the filter is staring at you. The oil plug and the access are horrible. The extractor is very, very effective.
Some cars have notorious reputations for having weak oil pan threads or plugs, and while you can't abandon getting below the car for the filter on all cars, if you don't want to turn that plug you can extract the oil from above or replace the plug with a petcock valve (if possible). In some cases, you can run a tube from the drain valve to direct oil.
On some cars or boats, an oil change interval that happens twice as often as a filter change is not out of the question either. In marine use, you might only do one filter change per year, but the difference between oil weight in March and July is such that you need to switch oil (which could be engine out service without a pump). Filter can stay put. In an early turbo car from the 1980's, I might change the oil every 2000-2500 miles and the filter every 5,000 miles.
