I was having a lot of top end rattle when I first bought my 93 Ex last summer. I tried thicker 20-50 oil but that just dropped my gas milage. A better mix has been mobile 1 10-30 and blue bottle STP oil additive. It's very thick and sticks to the mettle parts very well. I can report after recently driving my X on a 1,000 Journey to Las Vegas, down to Death Valley and then up and over the Sierras with lots of climbing up to 8K feet through the passes that my X is running very smooth with little top end noise on the steep hills and I was running 87 octane. I am happy to report after changing my EGR valve that the idle has smoothed and my trip gas milage on my 2wd 93 ex was between 18 and 21 mpg with my Land Terrain tires. I believe it has also helped for me to have changed my radiator and hoses because this trip my Ex was running much cooler than last summer when I made the same trip through the dessert(yes it was cooler this month). When I pulled my old radiator there was a lot of junk between it and the air conditioning radiator which is in front of the engine radiator.
I have used STP in other vehicles with simliar results. It does a great job of quieting things down. If you do a lot of hill climbing or have a lot of top end rattle, give it a try. I almost think it's better than Slick 50 because it goes in every oil change. rc
