I use the OEM filter. I am curious into what do you mean by oil pressure loss at the start up of your Mo. Do you mean that you lose oil pressure once it has started or that it takes a second or two to pressure up enough to clear the low oil pressure warning light ?billy bronco said:What oil filters are being used out there? Are you all sticking to the OEM brand? I'm having oil pressure loss at start up and was wondering if the Bosch I'm using is not good for this car.
I seem to have no oil at start in filter as engine makes large knocking every warm started. Takes a second for light to go out too.Stoker said:

It definitely sounds like you are experiencing some low oil pressure during startup. If Mobil One and an OEM filter doesn't fix it, then your engine may have been abused by the previous owner.billy bronco said:I just replaced with OEM @ $8.95
Started engine and the noise was the same as what I have been hearing before new filter filled with oil, even a little longer. Will be interesting to see what it does in the next few days, I'll let you know.
Actually, the only difference between Mobil One and the Extended Performance variant is a higher level of supersyn, which is Mobil One's antiwear agent. The antiwear agents are consumed as your oil ages, and the way I see it, if they can last 7500+ miles on a Corvette (which has factory fill Mobil One) with a 400hp engine, it will last at least 2500 miles on Nissan's V6 engine (even at 4000rpm).Cryogenix said:
Yup, you nailed it! I figure the 15,000 miles stuff offers even better lubricating and anti-breakdown properties than regular stuff, so it'll help prevent damage even more between changes.
Fluid changes are the single-most important thing to be attentive to in your vehicle for longevity...period! Unless your wife's in the passenger's seat...
I just changed mine to K&N oil filter. got it exactly same reason plus some better cleaning..... and before i put the drain plug back on.... did some magnetic charging on the drain plug......... for about 15 --20 mins.....Stoker said:one of the benefits of the OEM filter is that it has an internal check valve that will prevent the oil filter from draining down when the engine is shut down.
I have been using Mobil 1 05-30 in all my cars for over 15 years and highly recommend it for yours.billy bronco said:Well, I thought the start up noise was gone, but over time even using the OEM filter it still has a pretty good low end knocking when starting after sitting for an hour or more. Its not a good sound to me for sure and last for maybe a second. Sounds like a rod bearing to me, but I think its just something that has no oil at the moment when starting. Next I'm going to a synthetic oil as I see in several post this has helped many cars with similar issues.
What brand is recommended for my trial test?
i used to get about 380 km per tank on regular 87 grade fuel.Gonzo said:
Really 25-30%.... what are you getting now? The filter must have been pretty bad to increase that much.
