Is there a difference in the weights of motor oil 10/30 and 10/40?

Yes. 10-w30 will act like a 10 weight oil when cold and a 30 weight oil when hot. 10-w30 will act like ten weight when cold, but like (thicker) 40 weight oil when hot. Your profile only says Cadillac and doesn't say model or year, but most cars since the early- mid 80's use 5-w30. Always use the oil weight recommended in your owners manual. If you are unsure call the dealer and they will tell you what is right for your car.

Can I use 15w40 oil for the engine in a toyota corolla 1998 (gasoline)? Thanks.

Why not? You can use any weight you want. But,,, I run oil that is with the weather, We live in FL, and it gets hot here. 10w40 min. Multi-viscocity, It means your oil starts out at 10 weight cold, and as it warms up , it's 40 weight. The beads in the oil expand. A lot of people up north run straight 30 weight, I would want something thinner in there when it is cold out. So the multi stuff works great. Hope this helps.

There really is no better brand of oil, If you change your oil regularly, you will never have to worry about your engine. If you don't, it doesn't matter if you spend $5000 a qt, it won't do a bit of good, so pick a brand, select a weight in your temperature range, 10/40 is pretty common, maybe 10/30 up north, and get in the habit of changing it every 4,000 miles. I use walmart oil, it is cheaper, but I go through it fast around here, 3 cars, 2 bikes, lawn mowers. Hope this helps.

What motor oil weight should I be using on my 96 olds 88....we live where the winter temps can go as low as -10 F and as hot as 95F in the summer

5w 30 or 10w 30 during the winter. After an oil change... check your oil after 200-300 miles of use. Is the level the same? If so your weight is fine. If it drops, it's to light of an oil and your engine is now "drinking it" like fuel, move to a heavier weight. As far as Changing between winter and summer. Changing Oil weights is not bad for your motor so if the winter you go with 5w 30 and it works, great, shoot for the same during the summer. If it seems to "drink it" during the summer using this weight, go up to the next (10w 30)

That being said. Changing from natural oil, to synthetic, back to naturual , or vice versa... swapping back and forth between these KINDS of oil has been known to cause damage. so whatever weight you decide on, stick with one "type", natural or synthetic.

I have a 1998 sonata v6 5 speed gear box. In the morning when I first start off the gears seem dry/ and don't flow easily. Once the vehicle is warm all seems well. My son-in-law changed the gearbox oil as...

Try some Lucas transmission medic. Also make sure that you have the correct weight oil. The warm tells me that as the oil lube thins down it circulates fine. Adjust to a lighter weight oil.
