I have two jugs of 10-30 Restore and wish to apply a treatment(s) to the pride of South Korea Theta II GDI 2.0T engine clocking 111K miles. It uses half a qt of 0-40 by 2500-3K miles. I'm considering three options:
1a. Fill her up with 10-30 Restore topping off as needed until 5K or 1b. until I run out of Restore which might be up to 10K miles.
2. Blend one jug Restore with half a Qt V 10-30 "advanced" synthetic, leaving me 0.36Qt low, adding a qrt-Qt of Advanced as it uses a qrt-Qt for 5K leaving me with spare jug of Restore for future use.
3. Blend 2Qt Restore with 2.5-3Qt V10-30 "advanced" synthetic topping off with advanced until 5K, OC and repeat still leaving me one jug for later use.
I've blended four different types of the same brand oil for tens of thousands of miles, so I've no qualms as such with blending though none of those involved Restore. I'm not sure if half or thereabouts Restore blended would equal half the cleaning of straight Restore.
The small oil filter will surely need to changed out at least by 2.5K, within planned 5K OC, if not sooner
There was some very good discussion about the Restore within this thread, so I thought I'd camp here a bit and perhaps learn a mite from the Scholars of Earl. Grace me with your years of accumulated oil wisdom ye auld ancients of lubrication.
