I am always amazed at the huge mileage taxi and limo companies put on their vehicles, and the operating conditions are horrible for them in large cities. Stop and go, lots of idling, brutal drivers, etc.
Does anyone know what the typical oils are that these folks use and what kind of OCI schedules they run?

It was approaching 300,000 miles without major engine work. I didn't think to get any more info. I think Limos get less abuse than taxis. Kinda like high priced call girls vs street walkers.

Don't know, but I'd bet my mortgage it's typically a low-cost, name brand SL dino like Pennzoil, Valvoline, Havoline, etc. Whatever their bulk supplier normally offers. Some fleets (car and/or truck) might spring for synthetics I would think, but most have budget limitations they have to work with, limiting themselves to lower-cost products unless they can justify otherwise. Larger fleets can cost-benefit such stuff to death, but a small taxi or limo fleet?...I'd bet they'll simply use whatever dino the mechanic(s) are familiar with, maybe what they use for their own car/truck. From my experience, many of these small taxi firms are "mom & pop" in terms of their organizational sophistication.

From what I've seen locally and when I travel, I don't think cab companies give much of a hoot about maintenance. Something breaks or seizes up, they just grab another engine, part, whatever from a wrecked cab out back. ![[Big Grin]](images/icons/grin.gif){kind=icon}
Most cost-effective just to run them to death with minimal care since many cab commissions limit the career miles of a vehicle, they go out and buy another ex police car at auction and paint it. Gotta love the cabs in Memphis, take a Crown Vic, Marquis, Town Car, and spray the whole thing white or green, vinyl top included. ![[Roll Eyes]](images/icons/rolleyes.gif){kind=icon}
All that said, I know GM was using the Pittsburgh Yellow Cab fleet to test suspension, brakes, and trannys, so that whipped-out cab you're in may well have prototype parts for some future model in it.Our local police mechanic says that the local cab company buys some of the old cop cars and they just top off with the cheapest oil they can get..The new cars the cops get have their oil changed at 5k,they put in M1 and just add if needed til the car is gotton rid of.usually 72-90k.. ![[Wink]](images/icons/wink.gif)

The local Cab companies around here use the cheapest oil at Canadian Tire: Auto Lab. I don't know much about oil, but judging by it's price it's probably one of the worst oils you can buy. The owner/operators take much better care of their cabs and run their own personal preferences. Most cabs, even the severely abused fleet cars, see 250-300K miles with ease out of an engine. Better cared for units see much higher mileages. There are no age or mileage restrictions on the cabs around here, so there are many very high mileage units on the road, and some questionably roadworthy cars! The majority of cars are ex-police cruiser, mostly Caprices.
This has been stated multiple times before, but I'll say it again. BITOG members are perfectionists. Most could get by with any vehicle they own by doing the minimum maintenance with the cheapest filter and the cheapest SL oil at 5k mile OCI's. This vehicle will easily see 200k miles. However, we want to be better than that. We want to KNOW that our engines (and other mechanical components) are getting the least wear possible. We are fanatics and we like it that way!

I was in NY City about two months ago and my friend and I were talking about the Crown Vic taxis used. Even the Police use them. They last because domestic V8's are very good engines. The Ford 5.0 and now 4.6L are very good engines and will last a long time even on dino changed every 3k. Tough cars.
Most taxi's I've ever seen are hardly ever shut off.

Not true at night. even in nyc very few cabs around (compared to day) past 12 PM
Just about every late-'80's - mid-'90's Town Car I've ever seen leaves a belch of blue smoke every time the driver hits the gas. Judging by the typical blue-haired driver. I'm betting most have lower-than-average miles on their small Ford V8. They may be suffering from poor maintenance but that's still not a great endorsement for that engine.
So how many miles do the cab companies get out of their automatic transmissions? Anybody know what their service practices are for the trannies?
Some folks on this list think it's great if you get 100k on an auto tranny (don't know what kind of cars they are driving or what sort of driving they do) but most taxi's I've ever been in are abused by the drivers (IMHO). What about the trannies?

My uncle in NYC had a fleet of 10 yellow taxi cabs (Chevrolet Caprice's)in the late '80's. He changed the oil every Sunday on all the cars using dino Mobil 10w-40 for winter and 20w-50 for summer.
I remember he had a '86 Caprice with over 600k miles on the original motor. Only reason he took it off the road was because it wouldn't pass NY state emissions inspections.
The others lasted up to 300k to 400k miles.
Syntec Blend??? He must be a performance enthusiast ![[LOL!]](/forums/graemlins/lol.gif)
Most taxi's I've ever seen are hardly ever shut off. Depending on the climate, especially a very cold climate, you get a LOT of wear doing a cold start.
Since those hacks are always in use, and most domestic V8's are loafing along anyway, minimal wear.

My wife and I spent a week in NYC last year taking in the sites and going to some Broadway shows. We flew in and took a cab to the hotel. Everywhere we went we took a cab. I asked 5 cab drivers what oil they used and this was their response.
1. Pennzoil
2. Castrol
3. Whatever
4. Don't know
5. What oil??
The way they drive I should have asked what company they have their life insurance with.
The way they drive I should have asked what company they have their life insurance with.I used to work for the biggest wholesale and retail floral delivery company in Houston, and they leased their vans & trucks. As a result, they used Exxon Superflo 10w-30 in them on an interval of roughly once a month. I figure the average weekly mileage was probably about 200 miles, I figure that's about every 4000-5000 miles and this left plenty of room for time spent idling, etc...
No engine problems at all while I was there- plenty of brake, A/C, etc... but the engines seemed indestructible. (probably were- didn't the 1991 Aerostar have a 3.0L Vulcan?)
