More oil capacity...a bad thing?

SteveD2 · Jun 12, 2004

I've been planning for a while now on putting dual remote oil filters on my Jeep 4.0 engine. I'll probably get about 2 extra quarts of oil in there.

I'm starting to think that might be a bad thing for me, however. I don't drive that much, and when I do it's usually less than 10 miles on the highway. Not enough time for the oil to heat up. With 2 extra quarts of oil, it's only going to make the oil even cooler.

What do you guys think? Should I maybe not do the dual filters?

ZmOz,

For the conditions you just described I wouldn't do it. In most cases when asked, I would say more is better, much better; not in your case...and certainly not worth the trouble and expense to add the remotes.

Not worth the time or money.

Well, I'm going to be installing a remote filter anyway to make it easier to change, so it would only cost about $5 more to go with dual. Otherwise I'll just go with a single stock size...

I can only see cases o having too much oil capacity:
1. If the oil is never allowed to heat up. Not likely unless you have a very large capacity out of the engine or too big of cooler.

2. It causes you to not want to change the oil as often, and you overextend the oil. For a car that you don't drive much, I'd stick with a small capacity, since you'll probably be changing it with not that many miles on it.

If you do add more filtering, wouldn't you need to increase the oil pressure? Seems like after going through the extra filtering, that your flow would be diminished.

I have a dual remote on my 85 Volvo turbo because the filter is almost impossible to change normally. This is a dual remote - full flow, not a bypass.

I say 200% worth it.

Extra volume is not a bad thing, sure the oil will take a bit longer to warm, but just make sure you use the appropriate viscosity for the car. Overextending the oil? I guess....but you are an BiTOG member!! The likelihood of that happening?????

I'm thinking I might just go with dual stock size filters...instead of dual ~2 quart filters.

With a dual filter there will be more flow than with the stock filter, right?

I don't know why I was thinking they'd be serial. Yes, makes perfect sense. I need to go googling, and see what these setups look like.

Get the dual setup and run 2 small filters instead of 2 large ones.

i don't really think that dual filters really help anything for most applications. if you install it it will cost you the cost of 1 extra filter and 1 quart of oil for each oil chane. you probably aren't taxing the current system, an upgrade is just excess.

Pablo · Jun 13, 2004

tom slick - it really depends on the engine and sump capacity. I can tell you with experience there are some small cap cars that really do gain from just that little extra oil and the extra filter, especially most any gas turbo engine out there.

I've never heard of a car that isn't warmed up after 10 miles of driving 65+mph.

You won't have a problem, the oil will get plenty hit by then.

The ENGINE is warm, the OIL is not. No car's oil gets warm in 10 miles. The coolant gets up to temp after about 1 mile. I can tell when the oil finally gets hot because the oil pressure at idle goes from about 40 to about 20. That doesn't happen in 10 miles...

I'll come at this from a different angle,

how much of a temperature difference will it make with the added oil? A minute? Maybe two? (guess) How many of your trips would land out in that window? I would think not many?

The added oil capacity does not change the amount of fuel and water that make it into the oil, this is set by ring blow by and air volume of the engine, neither change with added oil capacity, but more capacity does mean more oil additive reserve to combat acids and other maladies

weather or not it is worth your expense or time to add the filters I do not know but many small gains can add up to something good

Zmoz,

By the time you make it to the highway, drive 10 miles on the highway, get off and go to your destination, what maybe 20 minutes? The oil will be hot.

Trust me, I drive my truck to warm it up for an oil change, the oil is hot, this is after a few miles on the highway.

I live 1/4 mile from the highway and usually my destination is right off the highway. And by 10 miles, I mean round trip. My oil does NOT get hot more than once or twice a month.

More oil capacity...a bad thing?
