I have a 94 Volvo 850 N/A with 294,000 miles that I just recently purchased. I am wondering what the best oil is that I should use. I would love to use synthetic, but the car has oil leaks that I do not want to make worse so I want to stay away from that. I really do not know how it is with burning oil because of the oil leaks, but I do not think it is that bad. The car does not smoke and the plugs are not oil fouled. My main concern is that there is some ticking at start up and I think it goes away after the car is driven for a while. I believe it is a lifter noise. I am using a WIX oil filter. As for the type of driving I will be doing, probably mostly city driving. It will get some highway miles, but how much really depends on if I feel like taking a lot of road trips or not. The car will most likely get driven every day and will not sit a lot. I also like to drive my cars pretty hard, like with hard acceleration and high RPMs. I have no idea what weight I should use because of the mileage on the engine, or if I need a high mileage. Any help is appreciated!
