Yes you can mix different brands but I recommend you do not mix different weights. You can even mix synthetic oil with conventional oil. But as the weight of the oil is critical, do not ever mix one weight of oil with another, no matter if it is synthetic or conventional oil.
You can mix part synthetic oil with full synthetic oil.
Yes, that is what a synthetic blend is that they sell.
YES! "Regular" oil is what is mixed with synthetic to make semi-synthetic. Try to use the same brand. I've heard it's not good to mix the different additives that different companies use.
Yes, you can. It is even sold as a Synthetic Blend.
Yea they take synthetic oil, make sure you don't do otherwise cause you can not mix different oils!
yes, infact, 95% of synthetics are about a 50/50 of conventional oil, and synthetic anyways. mix and match all you want, no harm will be done"95% of synthetics are about 50/50 of conventional oil and synthetic..."That statement is not factual. If the bottle is labeled synthetic than it is 100% synthetic oil. If it is a blend, it will be marked as such.If possible, do not mix oils as the additive packs are different. stick with what is in the crankcase unless it is an emergency and you have no choice.
Yes.
the oil mix is 32 to 1 or 50 to 1 for synthetic oil the oil mix is 32 to 1 or 50 to 1 for synthetic oil
Yes, semi synthetic is a blend of synthetic and conventional oil already.
Synthetic and conventional oil can be mixed and used with no problem. That is exactly what a synthetic blend that you can buy is. A mix of synthetic oil and conventional.
Yes, of course you can. You can even mix synthetic with conventional oil.
