I have a 1999 Mercury Sable (an older car). Im going to get an oil change later on today. They use Penzoil %26amp; charge only 3$ more to use a diffrent oil. What is the best oil to use? I dont know much about stuff like that as you can tell. Thanks for your help.Im getting an oil change on my car, What is the best oil to use.?
The expensive one that all I know.
whatever the cap or book for the vehicle says for weight and viscosity. as far a brand, i like castrol GTX but valvoline or penzoil is also a good brand and as long as you dont use those cheap ones at gas stations youll be fine. i also use the same brand every time. over and over. wifes car had valvoline so i used that in it. but i wouldnt worry about it youll be fine. im just weird like that.Im getting an oil change on my car, What is the best oil to use.?
penzoil is fine.don't use synthetic in an older car..its too thin and leakes out..Its more important to change oil and filter on time...3000 to 5000 miles..happy motering.
In some cases, you only need to change your oil every 7500 miles or 3 months.Im getting an oil change on my car, What is the best oil to use.?
Your car will be just fine on the Pennz as long as it is a multi-weight oil, 10W-30, 15W-30 etc. If you do a lot of stop and go driving or your commute is short, under 20 minutes. You can benefit from a SEMI-synthetic oil. You should still change your oil at 4000 mile intervals. There is no need to spend the money for a FULL synthetic oil as your engine was really not designed to require it. Hope this helps.
many things to consider. IN a 99, you are advised to use 5w-30 wieght oil. Pennzoil should be fine. But if you have noticed that you are burning or leaking oil then you might switch to a 10w-30 weight oil, or if it is really high in miles. Synthetic oil can be used, but if you haven't ever used it before I would stay away from it. It is kind of a dependency oil once you have started with it. The reason the company is charging more for other oils is that they have the Pennzoil in a BULK tank in the back and it comes out of a hose. cheaper than the bottles. Just so you know.
You can go with the Pennzoil.It's as good a brand as you can get. Just use what ever the book calls for and follow the recommended change intervals and you'll be in good shape.
Basics for lubricating oil - a thinner oil when engine is cold and gradually thicken up when engine temperature increases. To meet this need - the multi-grade oil.



For newer car, 5W30, older car,10W40, may not be exact try to get the closest ones. Mineral oil you need to replace every quarterly or 5000 km. For normal synthetic oil, half yearly or 10,000 km. If you are driving a high performance car and use special formulated lubricating oil - refer to the commended interval

God no dont use pengunk(penzoil).Very sludgy oil 1 of the best is Castrol.I have tore down many engines that have been run on pengunk and terrible terrible slugde build up.
When I get my oil changed they always use Valvoline 10w30 or 10w40.
