Hey Everyone: My friends from Kentucky have purchased an '09 Toyota Rav 4 with the V6 and they are due for their first oil change so I offered to do it for them as a good BITOG-er. It seems that it has a cartridge style filter off the oil pan. So I went to Toyota and bought the filter element which came with a plastic nozzle drain thingy and 2 o-rings. I also bought 5w20 M1 to put in it, because I have nothing else quickly available in a 4 - 5 Litre jug at a good price. So my questions are this and I'm hoping you can help: 1) How easy/hard is it to do one of these Toyota cartridge filters on this engine. 2) Anything special I should know or think of for the first time? 3) Thoughts on Oil choice for this engine (No M1 bashing please) 4) How many litres/quarts does this engine take? (I know I can look in the manual, but in case anyone already knows) 5) Anything else you can offer. Thanks everyone!
