its about oil, when the label says 5-30 what is the breakdown or blend of weights ? we know there is 5 & 30 o.2weight in there is there also some 10 and/or 20 weight in there as well ? No.2 if the car says 5-30 on the oil cap, If i change the oil and only have 2 quarts of 5-30 & two quarts of 5-20 laying around is that ok to use. I live in honolulu Ir’s warm ! and I use syn oil in my car. ---

There isn’t any 5W oil “in there” with 30 weight and 10 or 20. That is not how it works. The first number is based on the the cold temperature pump-ability. The second is based on the viscosity of the oil at 40C and 100C. Both of the oil as formulated in the bottle. If you mix 5w20 into 5w30 you will thin the oil for hot performance and risk your engine, especially in Hawaii. The end result will be 5w25-ish. So don’t. Take the stuff you no longer need to the recycling. ---

my car book says oil of 5-30 or 5-40 is ok to use, If I put 2 quarts 5-30 & two 5-40 in would that be ok ? Elantra has 4qts in engine. thank you. ---

Hyundai recommends using **5W** - **20** or **5W** - **30** engine oil in the 2014 Hyundai Elantra in all temperatures, but you can opt for 10W-30 oil if the temperature will not fall below 0 degrees F before your next scheduled oil change. You can use regular or synthetic oil in the your Elantra without any change in viscosity.

Miles, these engines can have oil issues that cause them to fail. Rather than trying to blend your own oil, I suggest you only use the recommended weight oil in a synthetic and change more often than the severe change interval. Based on @It_s_Me chart, I’d say use 5w20. You live in a very mild climate that doesn’t drop below 0 degrees but the thinner oil will helpmyour fuel mileage and the synthetic will help prevent sludge. ---

No I’m fairly certain your BMW is supposed to get 0W40, which is usually labeled as “european spec” fully synthetic oil. Castrol and Mobil 1 are the big names for that particular viscosity ---

Castrol and Mobil 1 are the big names for that particular viscosity The manual I linked says high performance synthetics either 5W-40 or 5W-30…which strikes me as odd, I would’ve bet on 0W-40 too ---

> [@miles10](#): > > If i change the oil and only have 2 quarts of 5-30 & two quarts of 5-20 laying around Is it really that hard to buy the correct quantity and type of oil and FILTER when you are going to change the oil. Really if you can’t have the appropriate supplies at hand for an oil change, you shouldn’t be doing it yourself. Put the tools down and back away slowly, and no cars get hurt. I mean really what kind of nonsense question is this? ---

5W20 and 5W30 are recommended by the carmaker. A 50-50 mix of the two oils is entirely within the carmaker’s specs. No problem, no harm. ---
