I take good care of it. I ran Shell Helix Ultra 5W40 untill now, 4k-7.5k miles OCI. Total mileage 33500 miles. I want to try VST even though Shell was fine but i think the formulation got worse after SN+ and later SP approvals. Worse pour point and flash point. Found Helix Ultra Racing 5W40 which looks similar to previous Ultra formulation (SN with Ferrari approval) but not worth the money, 50% more expensive.
VST is currently 9.8$ / 1L which is ok. MTF-2 was 15$/1L.
LE - Amsoil SS 0W40 also looks stout but its very expensive here, 16$ / 1qt.
