Ph2 172 Cup
Looking a the standards on Castrol GTX (bog standard stuff not magnatec) it seems to meet the required A3 standard. But as far as I'm aware it's a semi-synthetic.
Since it meets the standard, any reason not to use it in a 172 cup? It's about 1/4 the price of fully synthetic so my plan would be to use that BUT change the oil much more frequently.
Thoughts?
