2014 Seneca 37TS questions

I posted a few weeks back that I was in notations with a Jacyo Seneca dealer. I bought it and drove it back to CA with 8500 miles on it. I have since taken it in for a oil change, replaced the fuel fuel filter and lubed the chasse to establish a base line since I did not have the service history. Other than a few rattles that I will chase down we are very happy with the coach. That said I have a few questions that I could not find after a search on this site?

1) how often do you have the engine oil changed or how many miles between oil changes?
2) does the air leak down when parked? I hear a slight air leak when I shut the engine off?
3) what tire pressure has been found to give the best ride and tire performance?

Thank you

Oil change intervals 15,000 miles. I think that is too long and for $60 I change my own. Did my first change at 5000miles gonna change every 10,000 miles or once a year.
My air suspension will leak down after a day or so of setting. I always start mine and using the resume button on the cruise bring the idle up to 1000 until it comes up to temp before I ever move. The suspension pumps back up after a minute or so. I can't hear any air leaks tho.
I run 95psi cold tire pressure but there is a guide for the optimal tire pressure per tire load.

Jayco Seneca

I have a 2015 Seneca that I believe is mechanically identical to yours. Jayco could make this whole maintenance issue much mor simple by providing a manual that details all maintenance issues and the like. For reasons I don't understand, they don't. You can purchase a Freightliner Business Class M2 Driver's and Maintenance Manual. I have one and though its confusing, it does contain a lot of information. You can see it online for free. Oil and oil filter changes occur either 15000 mi or annually, whichever comes first. Tire pressure, according to Michelin on the 22.5 inch wheels is 100 lbs, both front and back. If the 2014 has some other wheel size or tire manufacturer, you will need to look it up. Because you can get water in your diesel fuel, it is recommended to drain your fuel filter housing at each fill up. Hope this helps.

Thank you both. You are correct, to my knowledge there is no hard line on service intervals in either the Jayco or the Frieghtliner manual. The service personal at my Freightliner started to tell me 25000.00 miles between oil changes but I think he is mistaken. Thanks for the advice.

Hi Dan, I believe the Freightliner Tech may have misread the specs. Iím looking at the Cummins spec sheet and it reads 15000 mi or 24000 km, 500 hours or 6 months. Primary and secondary fuel filters is also the same interval.

Thanks, our company runs Ford Powerstroke trucks so I'm aware of the componets that will need to be serviced just not how often for this size of rig. We came from a V10. I'm liking the added comfort send power.

I know this is going to sound dumb, but how many quarts of oil does the Cummins take? I have always had trucks, a one ton Ram with Cummins 6.7 presently. Don't know it would be the same as my 14 Seneca TS. I just bought the Seneca last week with 2,700 miles on it so I am really new at this. I have the Freightliner book but it does not indicate how much oil or for that matter other capacities. The manual seem confusing to me. Thanks, Sam

I believe the oil capacity is 15 quarts. 74 gallons of fuel, 34 in driver's side and 40 in passenger side tank.

More air questions

I also was wondering how long the air "holds" in other's newer Freightliner Senecas. If my 2014 is parked for more than 6 hours or so I am waiting to build air next time I start the truck. One time I thought I even heard a small air leak near the rear axle after I shut down but I had no time to climb under and investigate. Other times when I tried to listen it was absolutely quiet. Maybe the airbags releasing air? Not sure.

Since we have an air system, has anyone installed air horn(s) on their Seneca? I hate the wimpy single electric horn and will either add a second electric or an underhood air horn if possible and affordable. I don't want an electric compressor when I already have chassis air, I figure if someone knows how we can safely tie into the air system the horn air solenoid could be actuated by the regular horn circuit. Having experience with trucks with air brakes, I know there needs to be a "priority" valve preventing the horn from depleting the air to the point the parking brake self-applies!
