Low Oil Pressure Light on Cold Start

[JFP in PA]

On the basic LN adaptor, we use the Wix 51042 XP; on the IMS Solution cars, we use the Wix 51348XP (the IMS Solution uses a different filter).

Don't be concerned about the filter's physical size, what is important are media micron pore size, the filter's rated flow rate, and the media quality. Either of these filters are more than sufficient for use on a big V8 engine such as the GM LS unit, their flow rates are way beyond what the oiling system can move, and their media is considerably finer in pore size than the factory filter.

Interesting, I had ordered the wix 51348 because that was the cross reference for the filter they gave me. Maybe it doesn’t make a difference but I do not have the ims solution, just a regular adapter. I just ordered the wix
51042xp. Maybe the issue can be resolved with the right filter?

That would be a good idea.

I ran down to autozone and got the stp equivalent filter, put it on, cranked it with fuse pulled, started up nice and smooth and took it for a drive and everything seemed fine, no lights, no weird noises. Not really convinced. Will try starting it without extra cranking in the morning and then following up with hooking up a pressure gauge. I also got a spare cartridge filter to put in to test with the pressure gauge and see if anything changes.

Any updates on this? I have the exact same issue with my 986 and the LN adapter. I changed the oil/filter a week before winterizing it and I noticed the low oil pressure light after a few cold starts. I decided to worry about it in the spring. I am not sure which filter I used - It was either the napa one it came with or a Wix (not sure if I have the XP ones). I did not have this issue last year. Shout out to JFP in PA, I always appreciate your help.

First check which filter number is on the car when the problem occurs to make sure you have the correct filter.

What I think happened was the filter was filtering out the engine restore additive I put in during the last oil change, and it was restricting oil flow since there is no oil bypass with a spin on filter. I found it in the filter when I removed it. Did you put any additives in the oil? I changed the filter twice and have not had a problem since.
