what happens if you put 10w30 oil in a car that needs 5w30?
My friend saw my oil light on so he put oil in my car for me but he bought 10w30 and my car needs 5w30.
Your oil is a little thicker when cold. No damage will happen.
Everything you ever wanted to know about oil and lots more --- http://www.bobistheoilguy.com/motor-oil-101/
It will mix.
it will be fine.. i've used 10w30 a lot.
The 5W and 10W defines how the oil will flow at 0 degrees. At operating temperature, there will be a completely insignificant difference between the two.
DO YOU RECOMMEND CONTINUE USING 10W30 OR RETURN TO USE 5W30 ON NEXT OIL CHANGE
it is just a can right? ..no big deal. just wait till next change.
No I put 3 qurts
i've used 10w-30 too ..no big deal. it tends to be better when u have put hi miles on the engine.
I agree with Jason that when you have high miles on your car 10w-30 is better even 10w-40. I live in really hot climate so 10w-40 is not bad on the engine. During the winter though on some cars the 10w-30 will be noticeable on a cold engine, your lifters may sound on start up, happened to me that is why i know haaha. just change to 5w-30 on winter if that happens.
Oh and your engine will be fine don't worry, but again your lifters may make a loud clicking sound for about 2 seconds while the thicker 10w-30 oil goes up through the engine during winter.
i have a 2006 Mercedes-Benz and when I got oil changed they put 5W/30 and they told me I had a slight leak in pan but the last 3 weeks have had to add 5W/30 every week and light is still coming on saying it's low, before I got oil changed it, I had no problems. that's why I am asking maybe it will help to go to the 10W/30 Synthetic am I right. Just worried because it is a Mercedes-Benz I always had older cars and had not problems like this
