I'm thinking about increasing my OCI with SuperTech Full Synthetic (STFS), but just wanted to learn more about how it handles 10K OCI
on engines that are tough on the oil (like ecoboost engines, etc).
If you respond, please list:
Your oil change interval in miles/months,
How many years you've been using STFS,
Your car year, make, model, engine type, oil viscosity you are using,
and if you've noticed any sludge/varnish under the valve cover that you think is caused by using STFS + 10k mile OCI for a long period of time.
Thanks
