Hi All,

During my 50K mile Service i used Synthetic oil and now after 5K miles i want to do the oil change. I don't think i noticed any difference during this period ..

As my dealer offers oil changes for free i am thinking of switching back to regular oil..

Does this cause any trouble ??

Thanks

Good question, I dont' run Synthetic, but I'm curious to know...

Just an FYI mars - you're not going to "notice" much of a "difference" after switching to synthetic oil. Maybe a little bit of fuel ecomony and WOT acceleration benefit. You may also notice that the car will start a bit easier in the cold (though the OEM battery sucks, thus minimizing this benefit). The majority of the *respected* oil websites say you can switch back with no prob, as long as the engine is in good running shape (seals, etc). Personally, I wouldn't. Others can chime in with their 2 cents.

No problem. If you drive you vehicle normally, non-synthetic is fine. Folks like me use synthetic because ... well ... we're anal about our vehicles and demand the best. And switching back and
forth between them is OK too. Note the manual says you may use synthetic which means you don't need to unless you want to. Some high-performance vehicles like Corvette and Viper have
Mobil 1 installed at the factory because the engineers can omit oil coolers and still have the engines live at high oil temperatures. Our TSXs don't get this kind of abuse in daily driving. Take the freebee dealer changes.

Oil is probably the most contentious issue on auto and motorcycle boards. Motor oil is a topic which engenders many myths, and is probably where most motorheads waste money.

The second one is about motorcycle oil but busts some myths.

Cliff notes: you can put the least expensive oil in your car which meets manufacturer specs and be fine.

I'm no expert, but I do recall reading several threads warning about going from dino oil to synthetic, and then back again. I would do some searching and additional reasearch first. I just recall that once you go synthetic, stay there.

WHY? But when the regular oil is free I see why not.

Also If its a acura dealer they should be using a blend not just straight dino.

It will not damage anything if you go back to regular oil.

Found this. Looks like maybe it was an issue, but not now...

"One urban myth surrounding synthetic oil is its compatibility with conventional oil. At one time, those who switched from conventional to synthetics had to stick with synthetics—there was no going back. Synthetics expanded the seals in the engine; then, when conventional motor oil was used, that engine sprang multiple leaks.

Now, while the companies don't recommend mixing or switching back and forth, one company's synthetics are fully compatible with others and compatible with conventional oils. The source of compatibility problems was high levels of ester in the earlier synthetics. Considering the consequences, it's best to verify this compatibility, either on the company's website or with your trusted mechanic."

Thanks a lot fellows..

Really appreciate your feedback..

I think i will take the risk of going back to conventional oil..If this engine can't handle (what ever little problems it may pose) it's better to find it now rather than at a lter stage..

At around 30k miles I started having the dealer do synthetic. It cost a little but I wanted to experiment. I never really noticed anything and I'm kind of a cheap bastard, so I've reverted to the free regular oil changes. I stand by my decision.
