Here's my best interpretation of a DIY oil change on a 2009 Si. From reading various posts, I found it to be helpful if you turn your wheels all the way to the left before putting the car up in the air. It helped greatly, as getting the oil filter off is very tricky. The oil filter is in a very akward spot.
Honda didn't leave us with much room to work with under the engine in order to get the oil filter off.
I had some trouble as the oil filter was on way too tight from the factory - this was the first oil change, my car only has 3600 miles on it, and I wanted to go full synthetic.
I used a variety of tools to attempt to get the oil filter off, and found only one tool that worked - a FRAM oil filter wrench - take my advice and buy one! None of the other tools worked, which I will show you pictures of so you do NOT buy them and attempt to try removing the filter with any of these tools.
I used Mobil 1 Full Synthetic motor oil, and a Purolator oil filter - Part No. PL14610. I like these filters because they have a nice grip to them, allowing you to hand tighten very well.
Step 1 - pull your car into the garage or up on the lift, and turn your wheels all the way to the left
Step 2 - Put the car up on jack stands, and be sure to place the jack on either side of the car in case one of the jack stands fails - this way you have a few seconds to get out from under the car since the jack will catch the car should it fall
Step 3 - Once you're under the car, take note of the oil pan which has "ENGINE OIL" etched onto the oil pan, this is where you can unplug the oil plug and start draining the oil. Get your drain pan ready because it's going to start gushing out, be careful because the engine oil will overshoot your oil pan. Make sure the oil pan is within close reach to catch the oil. Place some cardboard down on the floor to catch any oil that may overshoot the oil catcher. After you're sure all of the oil has been drained, put the drain plug back on and tighten it, being careful not to over-tighten. Use a 17mm wrench to tighten the drain plug, no need to torque
I tried to take a few pictures once I was under the car to show you where the oil filter was - it's very hard to reach, and this is where the FRAM oil wrench comes in handy.
Step 4 - Once you've drained all of the engine oil, get ready to remove the oil filter with this FRAM oil filter wrench. Position the handles up towards the engine so you can pull counter clock-wise to remove the filter. If you position the handles up towards the engine, you will have enough leverage to remove the filter
Step 5 - After you've removed the oil filter, install the new filter and just make sure its hand tight - do not over tighten!
Step 6 - Fill with oil - Honda recommends 4.6 qts in the manual
Step 7 - After you've re-installed the drain plug, the oil filter, and filled with oil, start your car and look for any leaks
Step 8 - Check your oil dipstick for proper levels
I do not recommend using any of the following tools to remove the oil filter, none of these worked for me, especially since the oil filter was on way too tight from the factory.
I helped with the change and I can say that although the location is awkward due to the extreme cab forward design, the only real PITA is the way they cranked that filter down at the factory. Unacceptable!
There is a thick heat shield that makes it harder but given the location of the cat and header I can see why they have the shield. Again it was done to increase leg and headroom in the front for sure.
But with that particular Fram filter wrench you are good to go..
The next one will take 15 minutes tops including the obligatory "cold one"!
