A side note: The 0w30 is particularly hard to find. Autozone and advance auto don't even carry the 0w30. I spoke to a Mobil rep. The 0w30 is suppose to be good to replace all Xw30 oil and it saves gas. I have it in my car, it certainly feels more powerful (compare to the 10w30 dino oil).

0w30 is completely synthetic oil. It really isn't necasary unless you are driving something very powerful, like an SRT-10 or a Porsche. Use it if you choose to, I'll stick with 5w for my Chrysler.

But thanks for the deal!

I think youre getting the wrong idea about the ratings... when it says synthetic, its completely synthetic unlike the synthetic blends, which i think is pure crap. Just think, 1% synthetic and 99% dino would mean its a blend, so unless u really wanna use it, make sure you know how much of each is in it.

ANd NO! dont mix regular oil w/ synthetic, youll get a bad result since the formula wouldnt mix well. Companies make their blends a special way before they sell it. If youre gonna try synthetic for the first time, ease the motor into it by buying BLENDS first for like 1 regular scheduled oil change and then switching over to pure synthetic from then on. Keep in mind it is not recommended to switch if youre over 50-60k, i forgot the #. As it will cause a high rate of sludge buildup in the valves. It is also not recommended to switch back and forth between dino and synthetic as these 2 DOES NOT mix well, which will lead to sludge.

But anyways bout the rating, 0w30 just mean its a less dense, making the car feel like its running lighter w/ less restricting, thats why you get better gas milage. While 15w30 would make it more dense, to offer more protection at the expense of gas milage. So with that in mind, you would actually wanna use 0w30 for daily driving cars vs the higher rating for performance cars.

Thanks ahead for the advice...

It will help reduce wear but it might cause leaks on the rubber seals.

Honda recommends oil change every 3750 miles in those extreme weather conditions for V6 engines.

Guess I am stuck in Dino world.

That's based on the notion that you'd be using dino oil though. You should be able to roughly double that amount for synthetic oil. I all but guarantee that it wouldn't hurt your car in the least, nor cause it to wear any faster, etc.
That said, if you're under warranty and have a claim, they might argue with you having strayed from the maintenance schedule. If you actually do stick to the 3,750 every mile oil change, stay with the dino oil. I'd call it overkill but it certainly can't hurt...and I find that doing an oil change is a good opportunity to notice other things that might be wrong or about to go wrong.

Not like the honda engine would die; but I didnt want my warranty being challenged in case my luck runs out.
Also, my dealer charges $9.95 for oil change with Mobil 5w-20 and original Honda filters.

PM at Pep Boys and use B3G3 Free coupon.

I always change oil at Honda dealer. Does anyone know whether honda dealer use synthetic oil for Accord, as recommended by the manufacturer. Honda recommend an oil change for every 10K miles, which can only be achieved by using synthetic oil.

What's with all agents and touts for engine oils in this thread ?

Not to pile on the stupid questions thread. But heres a quick on.

1995 Maxima using 5 and 10w since I bought it last Feb. I have no idea what the previous owner used. I get my changes at WalMart with the basic oil for 14 bucks. I am approaching 150k on the vehicle. Should I do anything about the oil to prolong the engine, or keep truckin with that I am doing. I am about to drive 19 hours straight as well for moving day.

So should i be putting 0w30 in my viper? I think i/they've been putting in 10w30 syn

No, your warranty won't be affected. Basically it doesn't matter if you change your oil at every
2999 mi, 3001 mi or 5000 mi. There is no definite mileage limit, as there can't be. The key is
to take a reasonable care of the car. If something were to go bad with the engine, they'd probably
take a sample of the engine oil, and then they can tell if it's bad or good. And go from there.

And besides, if, say, the radio goes bad, could they blame the oil for that? What about the battery?
Fuel injector? Where do you draw the line, anyway?

The issue of synthetic oil seems to have a lot of beliefs and old-wives-tales around them, many of them
which may have been true at some time, or in some cases, and many of them simply untrue.

Actually, in Europe, synthetic oils are much more prevalent than non-synthetic oils. Up in the North,
where I'm from, that's pretty much all we put in our cars. And generally, the oil is changed
around 10000 km (about 6000 mi), but service manuals recommending changing at 20000 km are not unheard
of. And this is according to the manufacturer's specifications.

Are the engines in cars sold in America worse than the ones over there? I don't think so. Are the
driving conditions harsher? Not usually, unless you live way up North, way down South, and do a
lot of towing.

The only negative thing really I can think of with synthetics is the price. But you have to remember,
that it is offset by the longer change intervals.

Hope this helps someone.

Unless you have a pre-2000 Honda, then the 3750 is what the DEALER recommends, not Honda. Newer Hondas do 5000 on dino for severe schedule and 10,000 on dino for normal schedule.

For all those looking for 5W20, Mobil has relased 5W20 Mobil 1 recently, but until then the 0W20 was the replacement. It worked fine for 2 years in my Si.
