Can I switch back to synthetic oil without flushing?
Okay, here's the deal, bear with me it may be hard to explain:
At around (just guessing) 5000 miles I had my new Honda serviced and they recommended I change the oil because even though it was only 5000 miles it was over a year old. They explained that this would make the car run better and last longer so I went for their medium grade synthetic oil. Then, about 5k later I took it back to the same dealer and asked for an oil change. Not knowing that you shouldn't change back to regular oil without flushing I told them to put in regular oil. They did. Now it's 5000 miles later and my light came on for the first time indicating 15% whatever, for an oil change. I mentioned that I had put synthetic oil in it once but now am thinking of sticking with regular oil. But the guy told me that synthetic oil and regular oil don't mix and any time you start with synthetic oil, you have to stick with it or else do a flush first. But then he said, "But with synthetic oil you don't need to change it as often, so you don't really need an oil change even though your light came on." As you can imagine I am now totally confused. First of all: Shouldn't the dealer have told me the first time that once I started on synthetic oil I had to stay with it forever or else flush the engine? 2nd: When I took it in for the 2nd oil change and told them to put regular oil in it after they had put synth. in it the first time, shouldn't they have told me, then: No, we can't do that. Your car has synthetic in it, so we can't put regular oil in on top of it.? 3rd: Why did my light come on, saying 15% if I don't really need to change the oil? Is it set according to time, or according to how the oil is breaking down? (The guy at the shop today said it was just set by time, to light up after 5k miles. But if that's the case, why has it never gone off before now? (I have a little over 15k on it.) 4th: How many miles SHOULD I have gotten on the synthetic oil before changing it? And now that I have changed it anyway, what damage have I done by switching back to regular oil, and next time should I go with synthetic or regular?? I think someone is b.s.'ing me. Is it the dealer who sold me the synth in the first place, or is it the mechanic who is now telling me I should always stick with synthetic oil and can't change back to regular oil without flushing first? And since I have already changed back without flushing, what harm was done? |

And since I have already changed > > back without flushing, what harm was done? Thanks for the reply and links. I called Honda and confirmed that I had indeed switched back to regular oil last time I went there. The guy there assured me that the type of synthetic oil I had used in the first place was something like a "half and half" type and so it allowed me to switch back and forth so there was no harm in switching back to regular oil last time. However when I told this to the independent mechanic who is servicing my car today, he said, "What? That's crazy!" But I assured him that I had already switched to regular oil last time so I may as well use it again this time. I read some of the threads about synthetic oil and it sounds to me like it's controversial at best, in terms of whether or not it is really "worth" the extra money. Since regular oil changes for my car go for around $22 on sale and synthetic goes for about 3 times that, I am skeptical as to whether or not it's really worth it, especially when I am the kind of person who changes his oil every 3-5k instead of the 15k so Honda recommends. One question though: Using regular oil (OR synth oil) is there any problem with changing it TOO often? The guy at Honda last time said he really didn't recommend I change it after 5k miles, and I was kind of shocked that he would say that given that usually they are looking for ANY way to get me to spend more money there... |

The second guy. But he may not be BSing you; he may be genuinely misled. A lot of people believe that nonsense. > And since I have already changed back without flushing, what harm was > done? None whatsoever. You can change from one to the other with each oil- change, if you wish. -- Tegger |

And since I have already changed > back without flushing, what harm was done? the guy's just trying to sell you the more expensive stuff - particularly because you've been talked into it before. conventional/synthetic oils are completely intercompatible. synthetics are often better, but i'm not sure it's not worth using them if you're going to change the oil that frequently. stick with whatever you prefer. imo, synthetics are worth the money because they have premium additive packages that keep your seals in good condition, last much better, they do provably protect better, and they offer slightly better fuel economy. if you're going to use them, leave them in for the full manufacturer specified change interval or the one per the engine computer, not this 5k mile nonsense. and do NOT get an "engine flush". very bad. -- nomina rutrum rutrum |
