I have a 1995 Nissan Pathfinder 4x4 V6 with 118K miles, that is giving me
some minor trouble.

1. Upon starting, I sometimes hear valve tapping sounds coming from the
engine, which would mean to me that the oil is not circulating properly.
This quickly goes away after 3-5 seconds. I just changed the oil to 20w50,
and I added some Lucas heavy duty oil stabilizer. The problem went away only
for a few days.

2. I get a slight exceleration knock using 87 octane fuel. I added Marvelous
Mystery Oil, but the problem quickly return a few days later.

Any suggestions?

Thank you

I would think 20w50 would make it worse if the problem is lack of
circulation at startup. Use 5w-30 per the manufacturer's recommendation and
make sure the oil filters you are using have anti-drainback valves. How
often do you change the oil?

Try a different brand of gas, or fill it up at the 89 pump and see if the
pinging stops.

I change the oil every 3000 miles, and I use a Fram 3682 filter. I will try
5w30 on the next oil change. I will a tankful of 89 octane, to see if it
makes any difference.

I just did a little research on the Fram 3682...it seems to be a poor choice
for an oil filter.

Any recommendations?

Why not try a Nissan filter from the dealer? They should be around $5-6.
That way you at least have some assurance that you have whatever the engine
was designed to use.

Wouldn't that be "piston slap" ?
There is a piston slap problem on some 95-96 VG30 engines. I don't
rememer the details but a google search will gibe you more details on
this.

My local Nissan dealer is a rip off. $15-20 per OEM filter. I have seen
Nippon filters advertised for $5-6. Is this one ok?

Could be. My '96 Honda developed that problem at about 50,000 miles. The
oil filter is a cheaper test to do first though.

On the Honda the fix was to either ignore it or replace the engine. We
chose to ignore it. Strangely enough, after another 60,000 miles, it went
away by itself.

Ask for internet discount, your Nissan filter should be around $4-$5 ea.
I've bought from both, great price and service.
