What weight motor oil should be used for my vintage car?

I have a 1984 Chry town %26amp; country, Labaron 2.6, the milage is 140,900 I usually change my oil every 1,000-1,400 miles. Since its almost 17 years old what weight would help keep it alive at this age? This car is well taken care of and almost every part has been replaced except for the engine and tranny..Thank youWhat weight motor oil should be used for my vintage car?
Actually your car is over 20yrs old, but thats not a bad thing. Most manufacterers will put a recommendation on the oil cap and when they don't its usually good to go with 30weight. 5W30 or 10W30, also with the miles that you do have I would also recommend that you use a high mileage oil because of the extra additives they put in to help the seals,bearings, and gaskets in your engine.





If you take good care of your car then it will last a long time. Also, I wouldn't recommend changing your oil so much, every 2500-3000 miles is just right.





Good luck and hope this helps.What weight motor oil should be used for my vintage car?
I have a couple older cars %26amp; I use 10w40 in them.
castrol high milage 20/50is the best for that car
I would say 10w30
It depends on the climate where you are. If it's a really cold climate, I'd go with 10w30, if it's a warm climate, I'd go with a 20w40.
Any quality brand of 10w30 would be fine. If your using conventional motor oil it would be OK to only change it every 3000 miles. Quaker State offers a special blend oil for engines with high mileage. If cost is not a factor synthetic motor oil would be an option. Synthetic oil offers superior lubrication with less break down so it can be run longer between changes and promote extended engine life.
10w40 oil used to be the ';standard'; for multi-grade oils when that vehicle was built but it does not hold additives as well as 10w-30.





For most parts of the country where winter is not close to zero degrees, 10w-30 would be fine for an all around, all-season oil.





The ';10'; refers to the viscosity at zero degrees F, and the 30 refers to the viscosity at 105 deg F. The viscosity will vary depending on the climate temperature. That's all those numbers mean. Make sure you use a good quality oil - any name brand or oil company oil (for example: Chevron).





The newer oils ';designed for older cars'; simply added a seal expander to help slow down oil leaks.





1000 to 1400 miles sounds a little premature, unless the time exceeds 6 months. A good interval would be 3 months or 3,000 miles; which ever comes first.
