We have a 93 accord with over 300k miles, and we'd like to keep it running without throwing too much money at it. It has a pretty minor oil drip, I think from the pan gasket. I normally hate hack fixes, but this car is really old. Is there a decent product out there that could work to stop the leak (without wrecking other things)? Is there a heavy oil weight I could safely use to potentially reduce the leak? I'm pretty sure it's running 10w30 right now, which was too thin for my other car and exacerbated a RMS leak - so the weight has me wondering.

 

Replace the oil pressure sensor, located directly above the oil filter, this is a notorious leaker. Less than $10 at Autozone. Additives are unlikely to fix anything.

 

Thanks! any other common problem areas to check out while I'm at it? Granted, with this many miles anything could be leaking.

 

If it's minor, I'd strongly consider just leaving it and watching it.

 

I generally agree with your statement - however, we're relocating to a rental house and I don't think the owners want an oil-stained driveway. The accord has left quite the mark (over a couple years' time) on the parking lot at the current townhouse.

 

It could be the rear main seal. Just drive the car until its hot, park it and look for the dripping. It will be where the trans and engine block meet.
