I need more info about your driving style,
how many miles is your engine had ?
your driving style is mostly city ? mostly high way, or both ? short trip ?
If you drive mostly city short trip, then buy any regular oil of your choice of filter, Napa gold, wix, pure one, motorcraft. and change it every 3k miles
if you driving mostly highway then get any synthetic ( mobil 1, quaker state, pennzoil, vavoline, of your choice with filter of your choice ( napa gold, wix, pure one, motorcraft, mobil 1, K&N ) and change it every 7K+ miles
If you got high miles engine, have few leak here and their, burn a little oil, then use any high miles engine oil, quaker state high miles ( 3K+ ), pennzoil high mile ( 3k+ ), vavoline max life high mile ( 5k+ ), mobil 1 high miles ( 7K+ )
if you driving alot high way, or long trip any regular oil can go up to 5k miles. Stick with any oil filter i list above and you will be fine, check out autozone, advance auto part, napa, oreilly.... for their ad, they alway have oil and filter combo for lowes price, like advance auto part having 5qt mobil 1 with mobil 1 filter for 28 dollar, cant beat that price.:2thumbsup:
