I bought my 2002 Infiniti I35 last August for a good price. When i first bought it I didn't really drive it and even now I'm not a lover of driving so I probably put on about 2000 miles since I got the car. It has come to my attention that despite me not reaching the mileage limit, I should really change oil since it's a year and some months old. I looked into changing it myself and at the moment but I just don't feel comfortable doing that right now (I only have the jack the car came with; I wanna buy some RhinoRamps in the future). Since I told myself I'd just go to a place to do it I started looking up stores nearby and calling them to get some figures. It turns out while there are $10 options nearby, I wouldn't trust it. I kept looking until I found a place known as Fleet Tire that has really good google and yelp reviews. Best of all, they have a coupon for 27.50 that includes tire rotation and a 24 point inspection (which I'm not sure what that is). Their full coupon reads: "Coupon Valid December 01, 2017 thru December 31, 2017 $27.50 Oil Change and 4 Tire Rotate w/24 point vehicle inspection -Includes Kendall 5 qrts Synthetic Blend 5w20 and 5w30 motor oil -Premium Oil Filter Canister -4 Tire Rotation -24 point Vehicle Inspection Bottled Oil, Full Synthetic, Cartridge Filter may be extra" I'm a very nervous person by nature and I just have knots in my stomach thinking i'm doing something wrong. Do you guys think that coupon is a good deal? Does anyone know anything about the Kendall brand of Oil (I heard those $10 oil places uses really cheap bad oil)? Do you think I should talk to them about that "bottled oil" portion of the coupon? What is tire rotation and 24 point inspection? I have a sticker on my windshield that reads 10w40. Should I not put the 5w30? Any and all advice and help will be greatly appreciated.
