Don't people realize as an engine wears.....your oil pressure drops.

Synthetic or conventional oil both will work fine. Skip the Lucas. Return it. Definitely go heavier 20W50 if possible. Engine will do fine with it in your region. Hopefully the tornadoes don't break out tonight down there. I used to live in Birmingham and tornado season was interesting. Amazing how everyone went on like nothing was going on during a tornado siren and how quick cleanup of downed tress would be. Next morning couldn't tell anything happened. Here it would take a week or 2 to get that mess cleaned up. It snowed an inch when I lived there though and city was closed down for a day.

20/50 conventional with 3000 mi OCI unless you have rod knock on cold startup in which case new bearings including mains before crank gets hammered.

It probably won't even make a difference but whatever. Does it matter whether the 20w-50 is conventional or synthetic? I didn't have much selection at my auto parts store so I don't know what they'd have. I can then save the one quart of 10w-40 and keep it in the trunk for emergencies, fill ups, etc.

Also, as you can tell I'm quite new to working on cars, so if I get the bearings replaced, I would most likely have the mechanic do it for me. Is there a time/price estimate for a job like this?

Thanks in advance!


Use the Valvoline 10w-40. Check your oil pressure, and observe the trend. If it still appears to be low, go with 20w-50 on the next oil change. I don't like running a thicker oil than necessary.

I can't comment on the cost for the mechanic to change the bearings as I've done all of my own work for the last 15 years.

I also agree with everyone else. Avoid Lucas Oil Stabilizer.

OP have you verified your oil pressure with an actual gauge? The cluster is not accurate. My ,97 XJ reads 10psi but actually is 25psi, spec iirc is 13+ warm idle

- I'd run 15w-40 or 20w-50 as stated.

Keep in mind, none of this FIXES the problem. Neither will an HV oil pump. If your bearings our worn out of spec, you need a bottom-end overhaul. The best you can hope to do is limp it along until you can afford to do so.

X3. Verify first.

Put in the 10W-40, and if it doesn't give you enough oil pressure, put a bottle of STP oil treatment in with it.

It does have some AW additives, and will bring the oil up to a 50-weight without having to dump perfectly good fill of oil.

You can add a pint of STP to a full pan of oil without over-filling it too much.
