If it is the synthetic blend, you should change the oil every 3,000 miles. If it is a full synthetic, you should change the oil every 5,000 miles.
Every 7,000 miles if you drive normally.
Yes, service stations will often call this a semi sythetic oil change.
I work for a lube distributor. It is fine to go from synthetic to synthetic blend. Here's the difference: No manufacturer will actually release how much synthetic is in their synthetic blend formula. It may actually be closer to a conventional oil than a synthetic oil. The benefit of synthetic is that it offers better protection for your vehicle/ machinery. The secret is that it only makes a true difference if you're one of those people who doesn't change your oil regularly. If you choose to go synthetic blend, make sure you keep up with how often you change your oil!
You can use synthetic, synthetic blend, or conventional oil. It is your choice.
Synthetic oil or a blend of Synthetic and regular oil is much better for your vehicle than regular oil alone. Synthetic oil is MUCH more expenshive. If you change your regular oil every 3 months or 3,000 miles I will be fine.
Every 3-4000 miles, but you can go as many as 5000 miles if you're desperate.
Yes
It is a combination of synthetic oil and conventional oil.
Yes, that is what a synthetic blend is that they sell.
You can use conventions, synthetic blend, or 100% synthetic, your choice.
Every 3,000 miles Ford recommends every 5,000 miles with normal oil or synthetic blend. You can go up to 7,000 if you use full synthetic.
