Oil choices can be a personal choice.
Every situation is different and the recommended oils are a good baseline to follow,but what works in severe service may not work for a car that is lightly driven on occasion.
I agree with carl_g a blend would be best.
A full synthetic would not be suited for a high mileage 2.2L.
A freshly rebuilt motor yes,but not anything with some wear on it.
The tolerances of today's new engine are tighter compared to the older technology of the 80's.
Hence the complaints of oil leaks with synthetic oils.
I run 10W30 Pennzoil High Mileage semi synthetic blend.
For the earlier carbureted 2.2's with flat tappets,I find it works well since it contains more zinc,and has a formula to reduce sludge build up,and also minimizes oil burning/consumption.
When I first bought my K,it had wicked blow-by.
After switching to the high mileage blend,the blow-by stopped.
Despite only having 90,000 miles on it,my K did a ton of sitting over the 30 years before I owned it.
Well that's my personal experience and hope it helps you decide what oil is right for your application.
