OIL FILTERS R.....T

What car and what engine?

Have you checked the oil pressure light itself?

Hi Davoe,

it may well be normal for cars and 4bys to be like this, but going on my memory (which aint all that reliable) it wasnt always like this. it does seem like a terrible amount of damage could/is being done on startup. is this a plot by the filter manufs in agreement with veh manufs to cause motors to wear out quickly and so the consumer (us) has to pay for repairs more often??

thanks

Bob

Bob,

I'll admit that I know stuff all about how this all works.

The only thing I can add is that my Patrol's light only stays on for about 15 seconds, and that used to worry me a bit too. Since fitting the Oil Pressure gauge, I now have a slightly better understanding of what is happening.

IMHO, it doesn't have anything to do with your choice of oil filter/s. The light is only their to indicate that a low pressure exists in your oil galleries. In my case the oil gauge (the sender unit is in a different location to the factory-fitted switch which controls the red idiot light), starts to move off zero about the same time the red light goes off. This indicates to me that my red idiot light must be set at a very low pressure....as soon as the pressure builds up to about 3 psi, the light goes off. Now, in your case the factory oil pressure switch might be set higher (or could be faulty).
If it was my vehicle, I would be fitting a separate oil pressure gauge so you could check what pressure is in the motor. It has certainly allayed my concerns. However, now that I've done it, I do notice that there is very little pressure at idle speeds once the motor is hot. In fact the gauge barely registers; maybe about 5psi.

I've always been a great believer in Slick 50 and have treated my current vehicle twice (10,000klm and 90,000klm). The testimonials from satisfied customers was convinced me. One was a trucking company from Brisbane. A Kenworth had had a major breakdown in the Adelaide Hills....a fan had cut out and the motor was overheating, but the driver couldn't stop where he was, so he had to keep driving it to the top. The motor had done over 1.2 million klicks and they pulled it down to see what damage the overheating had caused.....The testimonial went on to state that the cross hatching which is on the top of the pistons when new, but apparently wears off after a few hundread thousand klicks normally, was stiil in tact and the motor looked like it'd only done a few hundred thousand....
It's probably all BS, but it convinced me to give it a go. It's a bit like the Shu Roo I haveand the Counter-Act (electric rust prevention) etc......you don't really know they ARE working unless they fail.

Hope this helps.....Just my opinions

I was using Valvoline filters for a short while.... took 10 to 15 seconds or more seconds for pressure to come up.
Now back to Ryco- much quicker to get oil pressure. (Nissan TD42)

The ideal would be to have an electric oil pump which gets pressure up before start.
