hi sages- surmise the comparative shopping for various oil filter brands is like the argument which name brand oil is best. 240s call for 10-30 wt oil. on my first oil change on the 92 245 last year i bought quaker state and a mann filter. seems to run well no oil light. wide range of store prices for oils. wal mart seems to be the best price not only for name brand oil but also for their own brand super tech. this 10- 30 has the same sn or sl quality rating as the name brands and is listed for new cars. as you know the standard for oils keeps going up each year. did some research and was told that wal mart which buys everything in bulk to keep the prices down , purchases valvoline oil and puts their store brand on it. would think all would agree that valvoline is a top quality oil. what think you? another question- while mann seems a top quality filter its price is stiff- best ive found is 6.50. have used many kinds of filters since 65 and oils as well. have found no real difference in performance other than 3-4 k oil changes and using a top rated(s scale for new cars). my question is what has your experience been with the old classic purolator brand. have used that on my american cars for many years. they make one for the 240. may try it on the next oil change unless i am warned here not to. thanks tons oldduke
