Wait a moment then pull it out again. Check the level of the oil. If it’s between the high and low marks, you’re fine. (If it’s too low, add a little.) The high and low marks can be denoted by two dots, an “H” and “L” or a shaded area on the dipstick. The photos below show a Honda dipstick which has the two dots. Why not just read the level first time around? The first time you pull the dipstick out, it will have oil all over it and it will be difficult to tell where the level is. That’s why you need to wipe it on a rag to get a clean dipstick, then dip it back into the oil to get a good reading. More information on why you should check your oil level is here Checking your oil level. Checking your coolant level Again, something everyone can do. The coolant is the other thing your engine cannot go without. Every engine is different but if you check your handbook you should find where the coolant reservoir is. It will normally be bolted to one side of the engine bay or the other, and be a white semi-transparent bottle. Wait until your engine is cool and take a look at it – the outside should have ‘low’ and ‘high’ markings on it and the level of coolant inside should be between the two. Do not take the radiator cap off to check coolant levels. If the coolant system is still hot then it is still under pressure and the pressure release will burn you. Fuel / gas Will higher octane or premium fuel give me better gas mileage and/or more power? No. Sportier cars have higher compression engines which generate more power and require higher octane fuel to prevent detonation. That’s where the myth of “premium = more power” came from. If your handbook says “regular”, use regular. See octane and power for more information. Bodywork / paint Keeping your paint finish in good condition Only choose superior car detailing supplies to keep your car’s interior and exterior like new. There are plenty of decent quality waxes and polishes on the market today and if the last time you waxed or polished your car was over a decade ago, things have changed considerably since then. The wax and polish compounds are far more sophisticated both in terms of protection from fading, the look of the finish, and the ease of application.
