How to Accurately Read Oil Level on Dip Stick

Dipstick oil assay may audio a lilliputian goofy, but it works. Non to mention information technology's also cheap and quick. There'southward only 1 problem - figuring out what the oil on the dipstick really means. No worry. Sit tight for v easy lessons on reading your oil dipstick.

Lesson No. ane - Retrieving the Dipstick

• With the engine hot, park on level basis and close off the engine. Wait a couple minutes for the oil to return to the oil pan.

• Open the hood and find the dipstick on the engine - a metallic loop or grip sticking out of the cease of a metal stalk. If you can't notice it, your owner's manual should aid.

• With a rag or thick paper towel in 1 hand, pull on the metal loop or grip and remove the dipstick with the other. Wipe the oil-wet straight end of the dipstick and push it dorsum into the stalk you lot pulled it out of.

• Wait a few seconds and pull out the dipstick again.

Lesson No. 2 - Detecting a Depression Oil Level

• How much oil should be on the dipstick? Examine the end of the dipstick and notice where the oil ends. In that location are markings that betoken the level the oil should reach. Sometimes in that location are holes instead of marks.

• If the oil doesn't achieve inside the markings or holes on the dipstick, you demand to add at least ane quart of oil. If the dipstick is not showing an oil level, you lot need to add oil immediately. The amount of make-upwardly oil you would expect to add together will vary depending on the age of your car, blazon of engine, total mileage and driving atmospheric condition. The dipstick is your approximate for abnormally high oil consumption. Real concern begins at nearly i quart for every 1,000 miles (0.95 liters for every i,600 kilometers). It'southward fourth dimension to plan an overhaul if the problem advances to one quart every 500 miles (800 kilometers).

• Is it OK to exist a quart low? The sidebar at the lesser of this commodity can answer this question.

Lesson No. three - What If the Oil Level is Too High?

• In certain cases, the oil level may have risen since the last fourth dimension you checked or there is besides much oil on the dipstick. This could exist due to condensed h2o (from combustion), condensed fuel or a coolant leak - all are causes for concern.

• Fuel-diluted motor oil (from blow-past or leakage) can substantially reduce oil viscosity and thin additive concentration. The odor of diesel fuel fuel tin oft be detected right from the dipstick.

• Complimentary and emulsified water is harmful to the oil and the engine. For short-trip drivers, h2o condensation may be more acute if your engine has the flexible fuel vehicle (FFV) option and you are burning an alcohol-gasoline fuel alloy. It is important to call back that combustion produces water in your engine - more water than the fuel consumed. Most of the water goes out the tailpipe, but if the engine is absurd, much of it may condense in the crankcase.

• A unproblematic manner to detect water in used motor oil is to put a drop of oil from the dipstick on a hot exhaust manifold. If it crackles (sounds like salary frying) this is an indication of water contamination. Beware that at that place is some hazard that the drop of oil may grab fire. Read more about using the crepitation test.

• Brand new automobiles imported from Japan may have a high oil level due to brusque-run engine starts (equally many every bit 50) required when the vehicle is transported from the assembly plant, across the ocean, and finally to the dealer'south lot. In this case, an oil and filter modify may be merited.

• Coolant leak is a serious problem relating to loftier oil level. Come across Lesson No. 5.

• Whatsoever the crusade of the high oil level, the condition needs to exist apace corrected.

• Annotation: accidental overfilling oil into your engine tin can cause issues likewise. As the crankshaft rotates information technology will churn the oil, causing aeration and eventually sustained foam may form. This tin atomic number 82 to overheated motor oil, oxidation and a loss of oil force per unit area. Spongy aerated oil is difficult to pump. It starves the engine and critical lubricated surfaces.

Lesson No. 4 - Signs of an Anile Oil

• Oil is not like a fine wine that gets amend over fourth dimension. Instead, information technology ages at a rate that is influenced by driving weather, fuel quality, engine age, motor oil quality and climate. If non changed in time, your oil will wither and fail to protect your engine.

• So, let's take a close look at the oil on the dipstick. The oil should wait smooth and sleeky and somewhat transparent. If information technology has sludgy deposits or grainy particles of dirt, it's time for an oil change. The same is truthful if the oil looks besides thick, is as well dark (opaque), and/or has a putrid rotten-cheese smell.

• If you withal don't know whether you need an oil alter, consider doing a blotter spot test.

• Oxidized and contaminated oil volition lose interfacial tension. A simple test for interfacial tension is to identify a drop of used oil from the dipstick on the surface of water. If the oil drop spreads out over the water's surface (instead of beading up similar a new oil) it may be time for an oil change.

Lesson No. v - Signs of Coolant Leak

• Dark-brown bubbling or a dried crusty-brown residue above the oil level line on the dipstick could be an indication that coolant (water and antifreeze) has leaked into your engine. The oil on the dipstick might even look like chocolate milk. Never taste motor oil as a exam for antifreeze.

• Another prominent indication of coolant leak is white frazzle smoke that has a sweet smell. In this instance, the dipstick oil level may really rise, indicating a significant amount of coolant has leaked into the crankcase.

• To ostend a coolant leak, shut off the engine, let it gear up for an hour or 2, unthread the drain plug and apply a articulate glass or plastic bottle to catch the liquid. Because both water and antifreeze are heavier than oil, they volition puddle upward at the bottom of the oil pan. Collect a couple of ounces of fluid and immediately retighten the drain. Inspect the fluid for glycol and h2o. Glycol and water often await like a thick mayonnaise-like paste, depending on how long the coolant has been in the crankcase. You might also discover a sweetness antifreeze smell.

• If you take detected coolant in your motor oil, your engine should be taken in for firsthand service.

So there yous have it - dipstick oil assay in 5 simple lessons. Checking your oil level may never be the same.

Take you learned tricks, not mentioned here, for using your dipstick to analyze used motor oil? If so, delight share these ideas but beware, they might show upwards in print anytime!

Is it OK to Be a Quart Low?

Automakers and owner's manuals will frequently say it's OK to wait until the oil level falls below the add mark to add oil. Notwithstanding, remember the crankcase of near passenger cars today holds only nigh four quarts of oil. This ways y'all are running the engine with 25 percent less oil (1 quart), which may not exist wise.

Motor oil has many of import functions beyond just controlling friction and wear. Oil not only lubricates the engine'south internal parts, merely also helps cool the bearings and other frictional surfaces. The oil in the engine, therefore, serves as a estrus sink to get together up unwanted heat to transfer it by conduction or convection out of the engine.

Under typical driving conditions, running a quart low may not brand much departure in terms of begetting temperature or overall engine lubrication. However, the engine also needs to be protected under worst-case conditions, such every bit in hot weather, while towing or with an impaired cooling system.

Too, when you're 25 percent low on oil, y'all are likewise 25 percent low on critical additives - the additives that prolong the oil life and the engine. Additionally, when you are 25 percent low on oil there is less oil to disperse harmful contaminants, acids, soot, fuel, sludge and h2o that enter the crankcase.

When you do the math, a quart depression on oil translates to a 33 percentage increase in contaminant concentration. Plus, the remaining oil spends less time at residuum in the oil pan and more than time in the hot frictional zones of the engines. The added heat, shear and pressure will more quickly degrade the oil and its additives.

One time all of this is brought into the flick, especially the prospect of an extended oil change, for many car owners information technology's a practiced idea to add oil whenever the dipstick reads depression.

Don't await until it is down a full quart. If it needs half a quart, add one-half a quart to bring it back up to the full mark. However, exist careful not to overfill the engine. In addition to the issues caused from overfilling the crankcase, too much oil may cause leaks as the high-riding oil is more than hands forced past seals and gaskets.
