im just wondering what happens to a honda civic if you used 10w30 instead of 5w30 they recommend??

Question

im just wondering

Answer 1

If you live in a VERY cold climate, where there are sub-freezing temps in winter, you should follow the Manufacturers recommendation. In warmer areas, it's not that important.

I live in So. Ca., where freezing temps are rare, have been running 20W-50 oil since day one with NO problems after almost 90K miles.

What's MOST important is regular oil changes at 3-5K miles.

Answer 2

The first person is way off.

the first number is the "weight" or "thickness" of the oil.

the second is its viscosity which is its ability to withstand heat.

There are generally 3 oils available

5W30
10W40
20W50

At first you may think that you want the one with the most protection which is the 20W50. Unfortunately, having to move heavier oil around will strain your oil pump causing premature failure (probably just after your warranty runs out). it can be an expensive repair depending on the model.

You should use what the manufacturer recommends unless you live in an extreme environment. Usually north of Boston, many people use one grade heavier.

If you are worried about protection, consider a synthetic blend or full synthetic as they really do a great job of keeping your engine cool. We really a difference when people trade them in 10 years later using synthetic. i remember one van sounding like brand new after 10 years as the owner only used mobil 1.

PS: Using a heavier weight oil also reduces your gas mileage. That is why our civic Hybrids use a special 0W20.

Answer 3

The oil will be thicker in cold weather, and will make starting the engine just a little tougher. I doubt seriously, if you would ever know the difference between the two. You should or likely will, change the oil again before the really cold weather hits, so the next time you change the oil, then go ahead and put the 5W-30 in. Good luck.

Answer 4

Nothing should happen. Most car manufacturers suggest that you use thicker motor oil in the summer months. This way the oil doesn't get too thin from the combination of hot weather and the hot engine temp.

Answer 5

If the car is new, or near new, you might just experience a little pre-mature wear on the tight fitting bearings, and it might be a little noisier than usual, but, for the most part, not worry. Just change back to the 5w30 soon to avoid trouble.

Answer 6

It's too thick of a oil for your car but nothing SHOULD happen to it.

Answer 7

5w-30 provides slightly better protection in COLD weather, and it gives you slightly better gas milage

Answer 8

nothing its just a thinner oil
