Greetings Everyone: Its that time of year again to change the oil in my Duratec V-6 Ford Escape. I currently run Liqui Moly MOS in the sump and the leak is near zero, so I will be adding it to the sump again this oil change. I run the LM anti friction moly additive in the van. Mileage has gone up a tad but I think it runs better. Should I add a can of it to the Escape? This would give me both MOS and the friction modifier in the oil at the same time. Will running both additives be overkill or un-necessary? Will it benefit, or detract, from the performance of either additive in any way? The Escape runs 5K per year and is on a 12 month OCI. Its got 168,xxx on the clock. TIA for your input.
