It's not good buy for your wallet. for most are priced like they contain 50% synthetic and they do not.
If your conventional oil has synthetic inside, but doesn't say synblend on the front of the jug, then it likely only contains 15% synthetic or less. The laws for putting "synthetic blend' on labels is very lenient. It's really a joke that's not regulated well at all by our government. But it should be and we have a right to know wow much synthetic is in that synblend.
If your owner manual doesn't call for a specific grade or doesn't call for synthetic -only, then use whatever you want for California. Just stay in relative grade for what described in your manual.
Shouldn't you be more concerned about the add pack than what percentage of synthetic it is?
If your doing 50% blends, why not just go fs?
