So I went to change the oil for the first time since buying my FJ. Long story short, I cannot get the oil plug off the oil pan. I'm not sure if someone tightened it to tight, or it has some rust (the FJ sat for periods of time as it was my dad's, and he used his company work truck 95% of the time). I was going to do an oil change with an expensive "advance stage" oil filter made with hugh quality synthetic material or whatever (claims to be good for up to 20,000 miles with the proper oil) and advanced synthetic mobile1 (Also claims to be good for up to 20,000 miles with the proper filter), but I also have a coupon for a free full synthetic valvoline oil change at a local regional corporate shop. I thought I'd just take it in to them and get a free oil change that was still high quality, and I figured they probably had a lot more experience with "stuck" oil drain plugs, as this is the first time changing my own oil, ever. Well it wasn't there for 10 minutes before they come tell me they can't get the drain plug out. Manager said "they were gonna take an impact to it but I told em not to do that without talking to you first and at least having an oil pan on hand." But he said he was betting I'd need a whole new oil pan. So I'm gonna get underneath her and make sure the bolts that attach the oil pan aren't rusted and are loose enough for me to remove them. If they are, I'm thinking I'll buy an oil pan to have on hand, and take an impact to the drain plug. I figure worse case scenario is I strip the plug and have to replace the oil pan, which I'll already have. Best case scenario is it comes loose with the impact, didn't strip, bolt and oil pan are fine, and I'll return the back up oil pan. Is there any issues with this plan? Any tips or suggestions on how to loosen this drain plug? And, if the unthinkable happens, what's gonna be the prognosis if ibget up underneath this thing and the bolts that hold the oil pan are too tight or rusted for me to loosen? Any insight would be appreciated as I'm not mechanically inclined at all. I'm 28 years old, as I said this is the first time doing my own oil change, and this is the first truck I've owned. I'm pretty confident in myself and my ability to learn. I'm not some dumb kid who went to private school and doesn't know how to change oil or a tire or a battery. I have a fair knowledge of vehicles, and understand the concepts of basic and advanced mechanics. Its just something I've never had to do. So I believe I have the ability and know how to do this type of work on my own vehicle, I'm just running into obstacles. Please help!
