When doing your own oil changes, Do you??

Bit hard to fill a new Filter on a 100 series as they are upside down. Back when i had trucks and excavators. i always filled the Oil filter if possible.

Agree Duke,
Bit hard to do on a 1HD-t as well.
Only takes a second or two for pressure to come up, I don't rev it at all until it gets to the top end.

Had a VL dunny door 3Lt turbo that would take a little longer to get oil pressure up, just let it idle for a little while longer.

G/Day RA, .. In bit of a quandry here!...I'm thinking air locks,or premature lubrication due to not enough oil for that few seconds, times the amount of times you do it per year equates to unnecessary wear Maybe???....Then as others say the oil filter is upside down on some anyway, so there goes that theroy ..lol.

Axle,
I know what you mean, any vehicle that I have owned with vertical mount filters I fill, right or wrong I really don't know.

Some engines seem to pickup and get oil pressure very quickly after a change and other take awhile.

Many large engines have jacking pumps that circulate oil for a short time before they start.

On a rebuilt motor I've always cranked the engine with the spark plugs out to get oil to all the important bits before hot starting it for the first time. But yeah I've never filled the filter before hand after doing an oil change, never had a motor fail because of it and when it fires its only idling, it's not like I would rev the tits off it unless I had to run in a new cam or whatever and in that case the procedure in my first sentence would apply.

Agree. With a rebuilt engine or one that the sump has been off, I always pack the oil pump with grease, (to aid priming it) and fill the oil filter with oil if possible. On a normal oil change have never bothered.
On the Detroit series 60 diesel I used to fill the oil filters to the brim as they are screw on upwards so no spillage and stops you getting an air lock.
Filling car oil filters is a waste of time as most of the oil ends up on the ground.

Gee Roger,
that must be a small engine, my filter takes 1 litre to fill.

Have a good one'

Hi R, have to disagree with you there, you quote ""From what I've read most wear occurs in the first few seconds of starting before the oil is up to pressure"" that I agree with, so if your filter is already full it doesnt have to send the oil to your filter first it will go straight to the areas required but if your filter is empty then it will require 2 to 3 seconds of oil getting pumped to it first instead of the major parts of the motor, In saying this my old lux did 300 thou when I sold it, 2.8D changed oil and filter every 4k since the day it was new, never filled the new filter up as it was on its side so impossible to keep oil in there when screwing it back on, oil light stayed on for about 2 to 3 seconds longer after an oil change compared to when I did a cold start with old filter already in place. The petrol prados I had/have I flick the key off and on a few times to get the oil up to the to the filter, the 4L V6 petrol prado like to rev at around 1800 on start up when cold and I dont like it revving that hard while waiting for oil to get to the filter which on the 4L V6 prado is right at the top of the motor. I drain my'n at night before I go to bed, I like to drain it for as long as possible, you would be suprised how much extra you get out when its hot then let drain over night, h..............

HI

I own same 2.8D hilux, so I know what you mean. I guess we are assuming that an oil change results in an extra 2 seconds wear whilst the filter fills as opposed to cold start.
Iif there were significant negative effects wouldnt they'd advise to tip your motor upside down before starting after every oil change ! LOL ! ;-)

Granted if I had a huge D10 dozer which took litres of oil in the filter - then it might be a valid point. But in a tiny little car motor I can't see it being an issue.

My lux is on 260k and still going fine, I don't really want to sell it :-)

Yuk,
I thought all the dip sticks were in Canberra.
