How many miles are on your T4R? Only thing it helps with is breaking down sludge at the bottom of the oil pan. If you do regular oil changes on time and do not run it very hard then you shouldn't have too much buildup.
112,000 miles ish.
but yeah ive had oil changes every 5k since ive owned it. but i will probably still do it because i am not sure about how the previous owner was on the changes.
