Longer lasting engine maintenance

With synthetic oils it is best to read the ,actual, oil manufacturer recommendations for each brand of oil. Some claim that oil should be changed 5,000 , others at 7,000 and some even boast 10,000 mile oil change intervals. There are many factors that you should consider when changing to or changing any oil. The climate you live in , for instance . Do you live in a climate where it is hot all of the time. Driving conditions ; Do you drive most of the time where there is a lot of dust or sand etc.....The other advice that I find always to be good is to call the service department of the make of your vehicle and ask them what the factory recommendations are. That will ensure that you don't void any warranty that may be available for your vehicle. I live in the North East U.S. I change my oil in my NON-Synthetic vehicles at 3000 mile intervals and do it as "religiously" as possible...And I ALWAYS change the oil filter every time I change my oil. For the other vehicle that I own I use synthetic and change that at 5000 wether recommended or not. And I ALWAYS change the filter. Remember-The cleaner your oil is the less wear on vital engine components.......Hope this helps!

Go by the manufacture's recommendation as far as type and weight. As far as brand, it is subjective. Any major brand should have the proper amount of additives. If you are trying to decide between synthetic and dino oil, either is good as long as you faithfully change them at the recommended intervals. With older vehicles, synthetics seem to "find leaks".

Hi.

30,000 miles is about right for changing standard spark plugs. You can install upgraded (and more expensive) Iridium tipped plugs which are claimed to last up to 100,000 miles but on a standard vehicle 30,000 is the correct replacement mileage interval.

Stick to the vehicles recommended service schedule and never mind what your friend says! Afterall these service intervals are already designed for a vehicle running on unleaded!

Carbon build up on plugs has a lot more to do with correct oil and oil filter changes than unleaded fuel.

Hope this helps. Please do rate my answer

Oil is one of the most important items inside your engine. It has a dual function...it keeps internal components from touching each other and wearing out, it also serves as a secondary cooling system.
Oil also carries away debris and moves it to the oil filter, holding smaller particles in suspension to prevent deposits.
Your vehicle is like a person that has a bad kidney and must go for dyalisis periodically. If not, bad stuff in their blood will kill them.
In all the years I've been in the auto industry, I have never seen anyone that had an engine failure of any kind from changing their oil too often. I have seen hundreds that did not change their oil with disasterous results.
Manufacturers have attempted to capitalize on the fact that the oil products we have today are far better than those we had years ago.What customer would not want a vehicle that was maintenence free? Oil filters used today are a bit better than older ones, but are also smaller. They do not have the holding capacity needed to operate properly over extended change intervals. When full, oil bypasses the filter and continues along through the engine.
These are the facts...Now here is what I think.
If you intend to keep your vehicle for any period of time, use the best oil available (I prefer synthetics) and change the oil filter at least every 4,000 miles. Then, you could follow mfg change schedule with some confidence. With a good synthetic, you could actually run all the way to 10,000miles with a "halftime" filter change. If using conventional oils, I would prefer to see oil changed every 4K or slightly less, along with filter. Don't forget...the dealer only needs your vehicle to last as long as the warranty, and actually needs it to fail after that so they can sell you a new one.
You would likely want it to last far longer!!! This applies to all fluids...coolant, brake fluid diff lube and trans oil...change more often and everything lasts longer!!!
Good luck with your car!!!

Regardless of what dealer tells you, there is no such thing as lifetime fluid. Even the best fluids such as synthetics should be changed. Change intervals should be regarded as false as well...If you changed all the fluids once a week your vehicle would last far longer than it does...Obviously this would take up a lot of time and $, but reasonably engine oil should be changed at at least 4,000miles, trans fluid every 25-30K. Otherwise the oil begins to chemically change loosing it's ability to do it's job and also carries fine contaminants with it that begin to wear components.
