After how many track days would you change oil on the ep3 of you was to do mix track and normal driving?
Short filters are not preferable. They're for K-swaps where space is at a premium. They have the same level of filtration but less of it, so will not perform as well for as long as a standard length filter.
I just bought 2 gallons of 5w-30 Mobil 3000. Is 5w-40 or -30 better for your engine for normal driving?
Based on what? Have you taken samples of oil to get them inspected in a lab after using both types of filter? Or did you just put your finger in the air and guess because 'your engine hasn't blown up'?but stick to the maintenance schedule and there's no issue's.
Where are you getting it fit that price dude? ?If you do say 5,000 miles a year and 3-4 trackdays... I'd be changing it every 6 months
5l of Fuchs Titan and a hamp filter is about £27, so it's not expensive
