Amazing.
At first was skeptical on even trying this oil for the simple fact its expensive & might be overkill for my setup. Turned out to be the best darn oil money can buy. For my 15' Subaru STI - 450HP / E85
Its the first time I ever checked my oil after 500 of hard driven miles, that the oil is still perfectly clean - no smell of gas or any signs of dilution. Im very impressed.
Highly recommend this oil. Price is worth it & Thanks to IIR for having a ready to buy kit for the Subi. 🤙
