Is it okay to put 5W-30 Synthetic Blend into our cars? I plan on 5W-30 Blend and then next time, in about 5000 miles, to put 5W-30 Mobil 1 fully synthetic.. It's about time I change.
Sounds ok?

Instead of wasting money on blends that have unknown concentrations, just mix them yourself. Blends cost more than regular, but who knows how much synthetic is really in them; 10%, 25%, 3%, who knows.

Blends are nominally more expensive.. I don't mind spending an extra $5 to have Castrol's blend in my car, rather than my personal blend.
