What is the best oil I can use in a 93 Ford T-Bird with 150,000 miles on it. V8, 5.0HO?

Question

I am wanting to know what are the best brands? Should i use synthetic, synthetic blend, or just regular oil?

Answer 1

Hot Summer months. Castrol 20W-50.

Winter months: Castro 10W-40

Answer 2

Castrol 10w3o. 5/30 is too thin for that old a moter. Yes, you can go to 20w50 if it gets hot where you are. but be sure to change to a thinner grade when it even starts to cool off. Synthetics are good for engines with plus 40,000 miles but not what you want at 150,000. Half and half is o.k. tho especially in the winter. When it comes right down to it the differant brands don't really make a differance as they all have basically the same additives. I personally don't like the pennsivania brands as i have seen oil pressure drop when the engine gets hot.

Answer 3

if its in really good shape,and runs really good id use a Mobil one synthetic oil in it,it will make it last a lot longer and run better also i have put it in some real high mileage vehicles and seen some good results from it before,and it wont hurt anything to use it some people will tell you anything but the facts are it Will help,any engine do a lot better,you can always change back if you don't like it,but there's not much to not like about it,all it can do is help it,it cant hurt it,but it does cost a lot,but id at least try it,and see,,good luck i hope this help,s.

Answer 4

5/30 is too thin for an old engine. There's no reason not to go to Mobile 1. It'll protect better, last longer and hold up better in heat and cold. Stick with 10/30. Thicker oil doesn't protect better and it doesn't circulate as well.
That's a damn good engine.

Answer 5

Ok, I hate to say it, but oil is oil. Some companies just advertise better, hence the higher prices of those advertised oils. As for the oil you should use in your vehicle, start by checking your oil fill cap, it may say on it, but most fords used 5w20 or 5w30 from the factory.

Answer 6

nicely particular and no.. some situations the plug will become stripped from a lot use after that many miles. i might think of nevertheless the mechanic that replaced your oil final might have observed it. i'm asumming which you propose the drain plug using fact there incredibly is not any different "oil plug" We routineley changel oil plugs or maybe some oil pans that get stripped out over years of use. sturdy sign is once you circulate to tighten it and it won't tighten

Answer 7

10w-30 synthetic always use synthetic, although 5w-30 is recommended it all depends on your rings and a simple leak down test would determine the wear and tear on your rings and let you know which one to use all though either one is good as long as it is synthetic. Also i would recommend useing a motorcraft FL-1A filter

Answer 9

the thing with oil "and my old anoilizer from hoppes" is the grade eg aa the best af not so good in little writing on the pack and if you can hear the cams rattle go thicker oil 20w 60 if not go 15w 50.

Answer 10

I suggest Valvoline High Mileage Oil. I forget what it is called, really, I just buy it...... I have been using that oil in my high mileage cars that I have had. I have noticed a fuel mileage increase, as well as a reduction in smoking during start up, and to top it off, a drop in oil consumption! I love it.
try it, you may like it......

Goodluck,
Stevo.
