What kind of oil does a Ford Mustang use?

Mineral based oils are the “conventional” variety, or the "change every 3,000 miles" oil The newer the engine, the tighter the tolerances mainly because of advancements in machining The viscosity (thickness) Ford chose for the Mustang is based upon normal operating temperature, or 212° F.

What temperature do you put oil in a Ford Mustang?

The viscosity (thickness) Ford chose for the Mustang is based upon normal operating temperature, or 212° F. The operating temperature is important in your oil choice because oil thins to the correct viscosity at operating temperature. At room temperature (or in the dead of winter), the oil is too thick to be effective.

What kind of distributor does a 1968 Shelby 302 have?

The street 302’s and the Tunnel Port used a single point vacuum advance distributor. For 1968 only, a special high-performance version of the 302 was offered for the Shelby GT350.

What kind of oil do you put in a Ford GT350?

If you have a GT350 or GT500, you’ll most likely be using 5W-50 oil. For high-revving driving situations, 5W-50 provides a higher level of protection against sludge and buildup. We’ve also included oil filter options since you should be replacing that along with the oil.

Can I use 5w30 instead of 5W-20?

In general, it is not recommended that you use 5w30 oil (or any other oil weight) in place of 5w20 oil, as the slightest difference in viscosity can potentially damage your engine.

What's the difference between 5w30 and 5W-20?

5w20 is an engine oil type characterized by its winter rating of 5 and an oil weight of 20 in warmer conditions. It is less viscous compared to 5w30. 5w30 has the same viscosity rating of 5 during winter but an oil weight of 30 during hotter conditions hence it is thicker.

How much horsepower does a 5.0 liter 302 engine have?

The Dart heads were capable of supporting a great deal more power, but the limitation was the displacement, cam timing, and intake manifold.

What year did the 302 Mustang come out?

The 302 cubic inch engine was introduced in 1968 to the Mustang, one of seven variations of V-8s were available in the ’69–’73 models. It was designed with Federal emissions regulations in mind. Although it is a derivative of the 289 mustang, some parts are not interchangeable. In fact the block of a 289 cannot be used without some machining. Since the 302 crankshaft is larger, it requires a notched out section in the engine sidewall to allow the connecting rod end bolts to pass. If you are unsure of the parts you are using to build an engine, check tolerances carefully.

How many bolt mains does a 302 have?

All 302 engines with the exception of the Tunnel Port and the Boss have 2 bolt mains. The Tunnel port has 4 bolt mains and the 302 Boss has 4 bolt mains and is cross bolted as well. All 302’s drank regular gas except the Tunnel port and Boss engines, they gulped premium gas.

What was the 302 GT350?

For 1968 only, a special high-performance version of the 302 was offered for the Shelby GT350. The main features included: an angled, high-rise aluminum or iron intake manifold, a larger Holley four-barrel carburetor, and bigger valves of 1.78 in (45 mm) intake and 1.6 in (41 mm) exhaust. It had a longer-duration camshaft, still with hydraulic lifters. The heads had special close-tolerance pushrod holes to guide the pushrods without rail rocker arms or stamped steel guide plates. The combustion chambers also featured a smaller quench design for a higher compression ratio and enhanced flow characteristics. Additionally, high-flow cast exhaust manifolds similar to those on the 289 Hi-Po K-code engine further improved output. Heavy-duty connecting rods with high-strength bolts and a nodular iron crankshaft were also included in this package. Rated power was estimated at 306 hp.

Can a 289 block be used without machining?

In fact the block of a 289 cannot be used without some machining . Since the 302 crankshaft is larger, it requires a notched out section in the engine sidewall to allow the connecting rod end bolts to pass. If you are unsure of the parts you are using to build an engine, check tolerances carefully. Both the engines are 90 degree V8’s.

What is viscosity in oil?

Viscosity measures the thickness of a particular fluid where zero is the thickness of water. Mineral based oils are the “conventional” variety, or the "change every 3,000 miles" oil. The newer the engine, the tighter the tolerances mainly because of advancements in machining.

How far can synthetic oils go between oil changes?

Since synthetics are more pure, they can endure more between oil changes. They are not as vulernable to heat as mineral based oils, and they can generally go about 7,000 miles between changes.

What is mineral oil?

Basically mineral oils are your traditional, non-synthetic oils. The common engine oil used in older engines. To achieve the lowest start up viscosity and the correct operating temperature viscosity, additives must be used. These are called viscosity index improvers, or VII. The downfall, however, is heat. When the viscosity improvers degrade, you may end up with 10w-20 oil in your engine instead of 10w-30. Or worse. This is why mineral based oils have to be changed so often. Usually the recommended oil change is every 3,000 miles.

Is oil viscosity affected by temperature?

Oil is a funny thing that is directly affected by temperatures. In fact, the oil viscosity measurements tell you right on the bottle how the oil will behave in winter temperatures. What if It gets too hot though?

Can you raise the oil temperature of an engine?

Well, any one particular mod may only narrowly raise the operating temperature of an engine. If oil temperature does rise, oil coolers can be added along with a bigger radiator to keep things stable. Though, testing out higher oil viscosity may be worth tinkering with. It generally will not go too far though.

Is 0W-30 oil thicker than 10W-30?

In this case, the oil is thicker at operating temperature than when it's cold. Technically there is no difference between 0w-30 and 10w-30 at operating temperature, but 0w-30 is thinner at start up. The thinner oils are for engines with tighter tolerances and to reduce start up wear.

What happens if you don't change your oil on a Mustang?

Pistons, camshafts, crankshafts, and valves all need to move in coordination to deliver the performance you expect every time you turn the ignition. If it weren’t for engine oil, the friction would cause your Mustang’s engine to grind to a halt. Oil’s main duties are to lubricate your engine ...

What is the purpose of oil in a pony?

Oil’s main duties are to lubricate your engine and clear away sludge. It also improves seals and even helps with cooling. But to get those benefits, you need to select the right oil for your Pony’s engine. The wrong oil can shorten its life, cause leaks, and generally make your life unpleasant.

Why is low viscosity oil better?

That’s because oil with too low of a viscosity can result in metal-to-metal contact, which damages the engine over time. Low viscosity oil is also consumed at a faster rate and is more prone to leak.

Why is conventional oil thinner?

Chemicals are then added to make the oil thicker when it gets warm and thinner when cold. The chemical additives break down in response to time and heat, causing the oil to become thinner. Because of this effect, conventional oil needs to be changed more frequently.

Is synthetic oil worth it?

Generally, yes. Synthetic oil is worth the price. You’ll go longer between oil changes, and you’ll get the extra protection synthetic offers. A more interesting question is whether synthetic oil is okay to use in classic vehicles, like the first-gen Mustang.

Is synthetic oil the same as distilled oil?

Synthetic oil starts as high-quality crude oil and is then further refined. No two synthetics are exactly alike, and most brands are very protective of their formulas. In general, you can expect to find petroleum components, distilled crude oil, and a proprietary blend of additives.

Is 5W-30 oil the same as 10W-30?

That means a 5W-30 and 10W-30 oil will have the same viscosity once they reach operating temperature. What makes them different is how they respond to cold. The 5W oil will have an easier time flowing in the cold since it’s less viscous than the 10W.

What happens if your engine rings don't seal properly?

Eg: 5w/40 or ow/40. If your engine rings dont seal properly or your engine seals are a bit worn then you might get some leakage or blowby.

Is synthetic oil better than conventional oil?

A quality synthetic will always offer better wear protection vs. a quality conventional oil. That's proven science, and reason enoug for using a synthetic oil in any engine that you'd like to last longer.
