I don't change my own oil because of warranty concerns. I read enough threads of people having warranty work rejected due to "improper service" because they changed their own oil.

So, until warranty concerns aren't an issue, I change it not.

All the other vehicles get the oil changed by me, though.

 

I do pre fill mine, but I'm not sure that it's necessary. You just poured over 5 quarts of oil through the engine.

Some of it has to stick up there.

Well, going by the other engines I've worked on, pouring oil into the engine, it goes into the valve cover, which has drain holes into the lifter valleys, and then drains straight into the oil pan.

So just pouring oil in doesn't get it anywhere important.

 

Well I'm only on my 2nd F150 and like to do my own oil changes for a number of reasons. The two most important being that I know it is done right and it's cheaper.

I pre fill the filter about half way and don't spill any oil. I have been pre filling filters since my High School days. I pumped gas and did oil changes at a gas station for part time work. Pre-filling the oil filter was how I was taught. It made sence to me and I have always been doing it this way.

BTW If you keep your bills for oil & filters you will not have a problem with warrenty issues! Just ask the dealer.

However, in my service manual for my new '03 F150, every other service is "REQUIRED" for warrenty. There are things like rotating tires, checking brakes, etc. which I'm not about to do in the driveway. Obviously they want the busniness but you don't have to go to the dealer to have this done. If you go to another shop, just keep the work orders at home in a safe place.

I'll probably go to the dealer for the "REQUIRED" maintenance because they are close and their basic maintenance is reasonable. The parts guys give me discounts on special orders and maintanence parts (ATF, plugs, FL-830's) so I don't mind giving the dealer some business.

 

I dont pre-fill and mine doesent clatter. Maybe because I use Mobil 1?

 

I use Mobil 1 and I pre-fill. Does this make me retintive?

Of course I do have a nasty habit of driving the **** out of my trucks and they only last a couple of hundred thousand of miles.

 

I plan to switch the truck and my Nova to Mobil 1. I guess the truck will wait until after the warranty period, and my Nova isn't fully broken in yet, so I'll wait for a tad bit on that as well.

 

I just started pre-filling my oil filter in my new car simply because it is easy to do. However, a far as it being necissary, that's obviously arbutrary, I never pre-filled the PH8A filter on my '88 F-150, and it's still running well over 300,000 miles later....

 

I always prefill the oil filter. Most of you already know that the majority of wear on an engine occurs at the time of start-up when there is no oil pressure and the idle is high. Filling the filter helps to reduce this condition. Even if you cant fill it to the top you can still pour it in and let the filter absorb the oil into the element. You may get 300,000 miles even if you dont prefill but whos to say that you woul'dnt get 500,000 miles if you did? It's a small precautionary step that takes little effort to do so why not do it?

In the old days ........... following an oil change I would disconnect the coil wire and crank the starter in short intervals until I saw the oil pressure gauge register some pressure. Mind you though, this was in the pre-electronics/fuel injection days.

The great philisophical questions of "What Might of Been"

I always focus on "what is", and "what is" is working great forme....

 

My F100 is over 500k miles, it has had its oil filter prefilled .

 

I always prefill the filter. I fill it up once and roll it around till it's absorbed, then add some more untill it begins to drip when horizontal. I also wipe the filter seat. It doen affect circulation. Watch the oil light after prefill and it goes out alomost instantly. Not so with it dry. I also use the time under the truck to check for any leaks or other problems. I also torque to oil pan plug to factory specs.

Does anyone pre-fill their oil pump? The oil drains from there too so it is dry when you try to start your truck. Oh wait, thats insane...But I think the 2 seconds that it is dry and when the filter is dry won't hurt my engine since I change my oil reguarly, take care of it, and treat it nice. You can't stop all wear on your engine. Changing your oil every 3000 miles, using good oil, and a good filter is all you can aks for. Who cares if I get 500,000 on one engine without a rebuild. By then, the power output will be so low I wont be able to do burn outs whenever I want to or tow whatever I want to. I congradulate everyone that is atleast changing or having the oil changed in their vehicle. Thats all that matters.

 

No, the oil pump is no problem because the pickup is submerged in oil. There would be little point.

 

Oil pumps that are mounted outside of the block do need to be primed after they are rebuilt.

Just packing it with petroleum jelly was enough to prime a Buick oil pump so it built up oil pressure quickly would'nt become air bound. The jelly would eventually liquify and mix with the hot oil.

So yes, sometimes people do pre-fill their oil pumps.

Anyone running a pre lube system on their vehicles?
