What Happens When Car Oil Is Not Changed Regularly
-
older the oil, the easy it burns and release toxic smoke
-
oil might be too little to “transport” all the dirty dirt to the filter
-
lubrication effect decreases As the result, engine will be much hotter , which consume more fuels
-
decreased engine working efficiency but also scratches and damages other important vehicle parts. car runs out of oil, car owners might need to replace engine to the new one.
it;s based on how much your engine heat produce & how your driving speed effects engine heat.
if you running at higher speeds then use 5w40
5w30 oil is designed to operate at ambient temperatures as low as -30 degrees Celsius
Reviews
Mobil Super MGDO 5W-40 API SM/SL Fully Synthetic Motor Oil for Cars (3.5L
5w40 in the temperature range of -25OC to 35OC. On the other hand, 5w30 is used in the temperature range from -25OC to 35OC
5w 30 a bit price high but in reality its cheaper than 5w30.
5w30 has less than viscosity so it gives more mileage but when its heating gets thinner than 40.
warm climates that reach up to 35 degrees Celsius low as -30 degrees Celsius (outside temps)
5w40 if outside temperature is 40. (india 32-40 in summer)
Turbo needed for high temp vehicles
added additives
does synthetic motor oil expire (mobil 5 years)
Does engine oil get old and go bad?
right synthetic might last 50,000, but it get dirty (particles of soot and combustion products and small insects and detritus and debris and schmutz and water accumulate in your oil storage)]\
oil filter is a balance between longevity and particle size.
OIL GETS DIRTY AT THE SAME RATE whether it mineral or synthetic)
cleaning cooling and lubricating the engine, and as a result it collects carbon.
does NOT make oil dirty is non-use. Unless you are parked in a desert monsoon or something
“oil spoils! MUST replace every six months!” is a bit of marketing trick.
it’s not the age of the oil, it’s the fact all the important bits have gone “dry” .
Engine Oil Types & Grades
| ACEA | API | ILSAC | SAE |
| A5/B5

SN | GF-5 | 5w40
W=winter, 40 =(outside temperature, (viscosity level) |
A refers to petrol and the B.
ACEA C3 oils are Top Tier lower SAPS lubricants.
acea a5/b5 sae 5w-30
High temperature high shear (HTHS) viscosity of engine oils is a critical property that relates to the fuel economy
Higher Hths better wear protection
Lower hths better fuel &lower carbon gasee
So 10W-30 oil has less viscosity when cold and hot than does 20W-50. Motor oil thins as it heats and thickens as it cools.
10w w=Winter.
2nd number viscosity measure at 100c hot.
oil can be rated for one viscosity when cold,& hot
10w (thickness resistance) at cold, 30 hot (thinner resistance).
Oil gets thinner when engine gets hot for higher room cc bikes we need 10w 50 like that.
When your cc increase oil may change.
Excessive thickness can make it harder to start the engine, which reduces fuel economy.
oil viscosity your car’s owner’s manual
manufacturer recommend.
4-6 months or 3-5 or at least 5-6 months twice should be in a year.
Society of Automotive Engineers (SAE) graded this 5w-30
Numbers are viscosity (thickness levels)
The ACEA Association of Constructors of European Automobiles, is an auto manufacturers association
ILSAC (International Lubricant Standardization and Approval Committee) represents the interest of American and Japanese manufacturers to the API.
American Petroleum Industry is the primary standards body for engine oil in North America

Mineral vs synthetic oil
regular oil gets distilled and refined from crude oil. Crude oil is a naturally occurring liquid fossil fuel. On the other hand, companies prepare synthetic oil artificially from the chemical compounds with the goal of mimicking the properties of the natural oil. They manufacture it as per the demands of modern-day vehicles.
regular oil: high impurities, high wear, long to get heat when cold start, cost low but replacing cost equal, lower drain time Longevity (3-5 Miles vs 10-15k Miles)
old car’s oil to their vehicles are much worse:
,
Most cars use synthetic for 10000 KM.

classification of ACEA B3. The recommended engine oil is SF 15 W 40, API – CG4
Thinner viscosity more mileage but engine sounds.
How often oil should be change?
- depends on how long you’d like the engine to last.
- Based on how long your engine life lost.
- Lots of short, stop-start city journeys: Change the oil more often. Long inter-city journeys on a freeway/motorway, you can reasonable extend oil-change intervals.
Diesel engines inevitably produce a lot of soot & particulates
Cheap oil then change frequently 3-5. Synthetic 10k miles. Mile=1.5KM.
5Km or 6 months which is earlier.
Car owner manual recommend to change engine oil 1 year or 10 kM maintenance.
Maruti genuine oil.
Too much filling as bad as low. After filling start engine for 1 minutes &stop for 5 min then check oil.
