I have heard that there are %26quot;semi synthetic%26quot; oils that need to be used prior to full synthetic. Is that true? Or do I just start using full synthetic on my next oil change? How do I change from regular oil to full synthetic?Nope. Jump straight to synthetic. It's a machine, not a human. It doesn't need to learn to tolerate synthetic, lol.How do I change from regular oil to full synthetic?You can switch right over to a full synthetic without issues. Also, there is no issues with switching back and forth. The myths you heard are not true.How do I change from regular oil to full synthetic?you could just put it in there with the regular oil. but i recomend you to do a engine flush. then put the full synthetic in. and semi synthetic is a blend with regular oil and synthetic oil.How do I change from regular oil to full synthetic?No, it is not true. Just switch oils.How do I change from regular oil to full synthetic? Just change the oil. Change it the second time on the regular schedule because there will still be some conventional oil in there, then you can go to an extended change schedule.
Semi synthetic doesn't really have much of an advantage over regular oil.How do I change from regular oil to full synthetic?You can switch right over; but why? Is your car almost new? Older cars with wear will break you by having to add the costly synthetic. Even if your car is newer, you will try to go longer between changes which causes more wear because even if you change filters more often, much dirt and abrasive is kept in suspension (floating around with the oil) and acting like a lapidary, grinding things down microscopically. I've owned vehicles that were run on synthetic their whole lives and I've owned vehicles that were run on Valvoline their whole lives but changed every 3,000 to 4,000 miles, and those run on Valvoline but changed regularly lasted much longer. The only time I ever advised a customer to run synthetic was if the oil pressure took too much time to build on a cold engine (due to poor design- the oil pickup tube was too long, running the full length of the engine).How do I change from regular oil to full synthetic?Good advice Ray! My dad allways told me the most important thing about oil is that you change it. What you use won't make much difference. It's the changing that removes the contaminents. In order of importance...
90% make sure you have oil. Check it.
9% Change it regularly so that it removes contamination from the engine.
1% what kind of oil you use.
Within that 1%, it's probably a good idea to stick with one brand so that you don't have to worry about different additive packages reacting in some unforseen way.
If the oil gets contaminated with blowby, or moisture, it won't matter that it is synthetic. It still won't lubricate properly. I only use synthetic when the manufacturer recomends it. Even then, I do not extend the service interval.
I use Chevron iso-syn processed oil . It's nearly as good as synthetic.
