Getting ready to give my '85 Blazer a tune up. Oil change, new plugs, filters, valve cover gaskets, et cetera. She's sitting at just about 117k miles (all original) and I've only ran conventional 10W-40 oil, never tried any synthetic or high mileage stuff before. Pretty sure it's not burning or anything, but I can't exactly tell because it does have a slight leak (hence the new valve cover gaskets). I usually have to put 1/2 a quart or so in every few weeks to accommodate for the leak. Anyways, I was just wondering what you guys think of the high mileage/synthetic oils. I've heard mixed reviews. Some people say they noticed a drastic decrease in oil burn and others say it doesn't do a damn thing.
I was also thinking about trying out Auto-Rx (http://www.auto-rx.com/index.html) instead. It's $26 a bottle (shipped) but it's supposed to work great and you only need to do one application. Two applications are recommended for high mileage/abused vehicles. Problem is, it takes 3oz per quart of oil and the bottle is only 12oz. So, I would need a total of three bottles ($65) to complete the two application cleanse. I would still have to buy two bottles just for the basic application ($45).
So, what do you guys think I should do?
