Tip & How-To about SAE 5W-30 Fully Synthetic Motor Oil, 1 Qt

Synthetic motor oil - Does it last any longer than regular motor oil ?

No. It does not last any longer than regular motor oil. The oil filter cannot pick up metal particles that are 50 times smaller than the diameter of the human hair. They accumulate over time. By the time you have driven 6000 miles, these micro sized metal particles start to cause excessive wear on the engine. This motor oil still has plenty of life in it. But it must be changed no later than 6000 miles, due to an inadequate oil filter that cannot pick up micro sized metal particles. All oil filters allow these micro sized metal particles to pass right through it. If your car has the feature of % of oil life left, you still need to change the motor oil at or before 6000 miles, regardless of the % of oil life left. It does not matter what brand of synthetic motor oil that you buy. They all need to be changed at the same interval that was stated in this article.

After how many miles should I change oil in 2003 Ford F-150,V6, 2WD, regular cab, automatic transmission, gasoline motor pick-up?

It depends on the filter and oil you use. My last Crown Vic had 165000 miles with no problems.

I use the Ford Lube services when there's a sale or Valvoline blended synthetic. Around 4000 mile intervals has been good for me. Never went longer than 5000 miles on anything I have owned. I have owned over 50 vehicles, never had lube failure.

best oil to use in 2006 nissan maxima

Depending on the weather condtions where you live will determine the type of oil you should use. If you are in cold weather most manufactures for newer cars 2003 and up recommend 5-30 weight detergent oil. if it is hot you may want to go to 10-40 detergent. If you have the engine broken in say 30,000 miles I recommend my customers use 5-30 synthetic oil, it has better lubricating and heat removal qualities that regular motor oils don't have. also oil filters are important too. Iprefer fram oil filters, the heavy guard filters. they are more expensive but filter much finer particles. and last longer. So the better the oil and the better the filter the longer your engine will last. Don't use parfin based oil as it will damage your engine.

oil & filter change

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!!!
