When should I change my oil & what type of oil should I use:
First change your oil, before it gets dirty.
There are basically 3 types of oil. Pure petroleum based, synthetic blend and full synthetic.
The first type is the cheapest and has been around for decades. I do not recommend this motor oil or do I use it in any of my personal vehicles or would I use it in any of my customer’s vehicles. A lot of quick change oil places & car washes use it.
The next oil is made from a combination of pure petroleum & man made products. I use this in all my personal vehicles, our loaner cars, fleet accounts & almost every vehicle that comes into the shop. It has great lubrication qualities, long lasting & not super expensive. I recommend 3500 miles and longer for this oil.
The third is full synthetic. There is nothing better than full synthetic oil for lubrication & long life. The problem is its the most expensive and the oil normally gets dirty way before the additives break down so the oil needs to be replaced. This is a 5000 mile & longer oil.
Remember if it’s dirty it’s dirty, it needs to be replaced.
For an example, if I filled a bucket with brand new oil & added dirt to it, its new oil right but its dirty. That dirt & grit is what is circulating thru your engine & causing wear on all your internal parts.
I use full synthetic oil in certain applications, for high performance engines, when customers are really bad about getting their oil changed on time or if it is required by the manufacturer.
Oil is what keeps all internal components from rubbing against each other & wearing out.
Some vehicles now calculate when you should change your oil. If you wait for your vehicle to tell you than when the oil change is being done ask your mechanic his opinion on the condition of the oil & adjust your oil change interval from there if needed.
Bottom line, depending on your driving habits, engine condition & weather conditions you could check your oil level & condition at 3000 than 4000 than 5000 ect. When you find the mileage range when your oil is starting to look dirty than you know how long you can go between oil changes.
There is absolutely no reason you do not get 200,000 & more out of your engine, that’s minimum miles.
So if it looks like it’s getting dirty, change it.
The timing belt keeps the top part of your engine in sync with the bottom part of your engine. So when the valves are open the piston is in the down position. And when the valves are close the piston is in the up position. When your timing belt breaks or skips a couple of teeth the synchronization or timing movement of these components are incorrect which can cause them to strike each other resulting in internal engine damage.
This is an expensive repair because the cylinder head has to come off the engine & the damaged valves have to be replaced.
You will also be replacing the timing belt & related components at the same time.
Must timing belts are due at around 100,000 miles. At this time the timing belt, idler pulley, tensioner & if the belt also turns the water pump, then the water pump. You change these components and you’re good to go for another 100,000 miles. So save your money & perform the timing belt service when it’s due as per your vehicle maintenance schedule.
Don’t know your schedule, ask us & we will print it out for you.
Why and when do I need to change my anti-freeze?
Flushing your engine cooling system is as important as changing your engine’s oil. Over time and with temperature extremes, to explain it in a nut shell, your engine’s coolant’s protective additives are depleted & begin to break down. This causes your engine to deteriorate & rust from the inside out. That is why when something as simple as a leaking hose or something bigger as an intake gasket starts to leak it is because these components rotted from the inside out.
For these reasons we recommend that you not only replace your coolant but “flush” the entire system out. This in turns removes all corrosion, scaling, rust, sludge & contaminated fluid from the system.
A” cooling system flush” consists of first adding a cleaner to the system and running the engine until operating temperature has been achieved.’
Then connecting a machine in line to the system & removing all the old fluid & contaminants.
Next the system is filled with all “NEW ANTI-FREEZE” and an additive. This additive is a concentrated rust inhibitor & seal conditioner. It also has properties which raises the boiling point & lowers the freezing point of the coolant.
This service should be done about every 5 to 6 years or 50,000 to 60,000 miles.
