I have a question. I'm driving a 1980 Ford F100 Pickup truck with a 302 w/ 159k miles it's time to change the oil.d I've never had to do it because i just bought the truck now my question is when i get around to changing it should i switch to synthetic oil or stick with the cheap cr*p? also since the owners manual is vague what weight of oil should i use? Im from the pacific northwest so its gonna be 30-40 degrees in the winter and 70-80 in the summer. Are there any additives you would recomend i add to my oil to increase the life of the engine and are there any specific brands i should use. Thanks

Run the high mileage Auto-RX treatment through it using MOBIL Delvac 1300 10W-30 or 15W-40. Then one of the better 15W or 5W-40 oils and a BALDWIN B2-HPG oil filter. Or Mobil One 15W-50. I use both LUBE CONTROL and FUEL POWER and especially recommend the latter -- has been great in my 1971 Chrysler. The LC is more of judgmental call (or consider using Dyson Analysis for advice as do I and a number of others around here for advice on that product and all else.) http://theoildrop.server101.com/cgi/ultimatebb.cgi?ubb=get_topic;f=1;t=001211 (See also the thread on the 312 Thunderbird)
