Having a problem finding out which oil to use in in my 94 hyndai Excel. 10w30 or 10w40?

Question

My car didn't have an owners manual. And there's no sticker on it anywhere like there usually is tell you the oil type. If anyone know what kind I need please respond. Thank you!!!

Answer 1

NONE OF THOSE, 5W 30 IS WHAT YOU NEED.

Answer 2

In cooler weather it's best to use 10w30. In higher temperature 10w40 would be better. Any multi viscosity oil is good in a range of uses. In extremely cold weather an oil beginning with a 5 can help reduce wear when the engine is first cranked since it circulates easier before it warms up. I Hope this helps.

Answer 3

In the winter you need to use 5W30 because it's a thinner oil and it won't thicken up in the cold winter months. In the mid to late spring switch to 10W30 because it's a thicker oil and it won't break down in the warm and hot summer months. Always remember to use high mileage oil such as Castrol or Valvoline they are the best especially for a car with over 75,000 miles on it. Remember to change the oil every 3 or 4 months, this keeps your engine healthy and running good. The lower the number the thinner the oil, the higher the number the thicker the oil.

Answer 4

Do you've intake topics with you motor with that many miles. You both have the 5.2l v-8 or a 4.0l I-6. Your favor for 10w-40 over 10w-30 skill you desire something a touch physically powerful. first of all a 10w-40 would not propose you've a multi-weight 10 and 40. The 40 is the load w stands for a wintry climate approved kit and 10 is a designation for the oils chilly climate initiate skill, a 15w-40 for example wouldn't have as solid of bypass characteristics. however it isn't a fifteen weight that's purely a viscosity improver. nearer figures alongside with 15w-40 are better solid than say a 5w-40, because the 5w-40 would must have better viscosity improvers to finish the wanted job which opens the door for better breakdown. the alternative of a HDEO or heavy duty engine oil for both of those engines is a wise decision with the suggested mileage. it is going to shrink intake and help to guard the growing older engine with ever turning out to be tolerances. in case you stay in chilly climate i might want to run Rotella T man made 5w-40 HDEO, if in a warmth climate i might want to run the Rotella T 15w-40 or delo 15w-40. they're going to all be tremendous on your motor. I really have had both engines in Grand cherokees, and they love the oils pronounced, they are demanding to kill. also for better oil components flow to bob is the oil guy talk board.

Answer 5

Would not make any difference on that old of a car.
The 1st number is how well the oil flows when cold and the second number is how well it flows when hot.
Lower the number the thinner the oil.

If the engine is in xcellent shape with no oil leaks then using the previous mentioned 5w30 may result in 1 or 2 miles better MPG.

As a general rule a heavier/higher numbered oil is used to reduce oil burning/usage on a older car.

Answer 6

If price is not an issue, then go for the 10w40. In most situations, it won't matter which oil you use but, under very stressful situations (as, for example going up the Grapevine), it might make a difference (because the top viscosity is higher).

Answer 7

5W30..... The oil will act as 5 weight in the winter and 30 in the summer, for a small engine you want the 5W30 weight. The lower an oils weight number the thinner the oil will be and the better it will flow, this is important to small high reving engines.

Answer 8

Either is fine, 10w-40 if you have southern-type hot summer. If you are in a northern climate, then 5W-30 will give you much better winter starting. Most cars now recommend 5w-30, most quick-change places have 10w-30 in the machine.

Answer 9

usually car manufactors recommend 5w-40 in the cars built since the early 90's for gas mileage sake.

Answer 10

10w30 for the winter
10w40 for the summer

Answer 11

I have to agree with JACK OF TRADES here. 5w/30 fully synthetic is the oil to go for.
