OK, I want to do a review on oil filters. I use genuine GM ones, because I am happy they are good quality, and because the price is comparable with a lot of after market ones. I have a Turbo Diesel, so the filters tent to be a bit bigger than the ones for Petrol engines. The filters in my car, are of the cartridge type, although a lot use spin on ones. Mine is easy to change, and is done every five thousad miles. I do realise a lot of manufacturers say every ten thousand, but I prefer five. I always change the oil at the same time, but in my case, it is possible to change the oil or filter alone.
Let me tell you my system, firstly you need the car at normal running temperature, then drive it up onto your ramps, stop the engine and remove the sump plug, the oil will then drain into a suitable container, in my case a bucket. while the hot oil is draining, you can go about changing the filter. The idea behind doing it while the engine is hot, is that you need all the sludge out, not just the runny oil. If the oil is allowed to cool, there will be pockets of crud left in all the nooks & crannies. I allow my oil to drain for at least half an hour. The filter is removed, the 'o' rings replaced, and the new filter is inserted. After tightening up, the engine can be topped up with fresh oil, remembering to refit the sump plug of course. After the oil is poutred in, the engine is turned over to fill the empty filter, then the level can be checked again. My engine holds six litres of oil, you must have the right amount, not too much or too little. I always have a good look underneath the car after the next run, just to make sure there are no leaks.
I always use original equipment parts, including oil & filters, and think it is well worth that little extra expense.
I can thoroughly recommend these filters by GM. Now, when was yours changed last?
