The cheapest synthetic is likely better than the decent dyno oils, so would presumably help with vapour deposits in the intake system as well as combustion deposits. Wally's Auto Mart is also where I get my oil these days. The only thing different I can think of is going for a High Mileage semi-synthetic formulation that contains seal conditioners, which for me means trying to postpone changing the weeping engine rear main seal for as long as I can (the front seals can easily be done at T-belt change time). You can always buy seal conditioners as an additive and add a little bit to the synthetic. I'm sure half of what they recommend would be adequate. Extra seal conditioner will swell the seals even more, but that can also increase wear on the seals.
