In the US if you're not besting the EPA estimates you shouldn't be driving. Our fuel economy estimates are calculated by having a pissed off teenage girl drive the vehicles for a little bit while wearing heavy boots.

There have been a few turbo'd vehicles that seemed to have difficulty for drivers to get EPA numbers. I attribute it to operator error.

Re: Diesel People - Enlighten Me? (2014)

I really don't think that the CRD will beat the epa as the popular sentiment on here seems to be. If you look at the MPG of the diesel Touareg, ML, X5 and Q7 on fuelly it looks to be spot on of the EPA milage.
There are some diesel drivers who get extremely high MPG, but these are people who buy the car for the high MPG and drive accordingly...these people would probably beat the EPA with gasoline cars too.

I did the same research and came up to the same exact conclusion. I think in general EPA numbers are underestimated for diesel but I think this is only true for smaller vehicles. Seems like car's weight or engine size play some kind of a role here. For heavier vehicles/bigger engines it usually it is spot on.

And yes, if you drive like a grandma you can probably beat any of the EPA ratings.

I think 28 is what you will normally get. If you extra careful you can probably easily get 30 or maybe even more (10-20% more). My current truck's EPA highway number is 19 and I can get 23 if I drive like a grandma 50 miles per hour on local highways which is about 20% more.

Re: Diesel People - Enlighten Me? (2014)

OK, great info last several posts. Thanks...

Here's another question for diesel-heads... I drive my hemi on long road trips at 80-85mph fully loaded with gear and roof pod and get a very predictable 17mpg (calculated, not dash computer).. What would a CRD get t that load and speed? (I'm afrid to ask...) We're using more of the engine's power here, so please be honest, use experience, to answer.


As to why audi switched to diesel in LMP1... Not sure. Can you answer why they don't run in F1, rally, or put a diesel in their sports car? Diesel is a huge worldwide fuel. I am not chauvinistic enough to say they are wrong. It's world wide marketing, I assume. What will the 2014 Porsche LMP1 car engine be???????????

Well.. we know it can do atleast 32MPG.. the 5Speed EU/Aussie model already is rated at that in the EU (according to their rendition of the EPA)...

Re: Diesel People - Enlighten Me? (2014)

From my personal experience: Driven conservatively you should be able to beat the EPA estimate in any vehicle (Hwy). Driven normally, you will get less than EPA in a Petrol Engine and be at or just over in a Diesel.

I drove a gas Jeep Laredo rental for three weeks when on leave in the states last year. From West Virginia (Snowshoe) to my brother's house in Ohio, I drove conservatively and averaged 27MPG for the trip (calculated, but very close to the computer). When I drove to my sister in New Jersey -- I got 20 mpg for the first leg (didn't track after that).

Our TDI golf will average 40 MPG in mixed driving (me) and 38 (her: she's angry but not a teenager). On the Hwy, going 55-70 I'll get 48 MPG (rated at 42)! On an open Autobahn averaging 90+MPH, I get 34 MPG. (The BMW gets 16!). I don't bother being conservative on the Autobahn anymore.

YMMV

Our Laredo CRD WK2 hwy driving, fully loaded, + gear on roof rack (not in pod), + towing our Aussieswag camper trailer 1.3t, at 80mph, 21.5mpg calculated, not dash computer.
You can't beat a diesel for towing and/or hauling a load, that's just another reason I've owned diesels for the last 8 years straight

I can't say exactly but I know my RV weighs 50,000 pounds and I get 9 mpg. (Verified by Cummins Technicians doing a real world test on my RV).

When my GMC Yukon Denali was towing an 8,000 pound trailer I got 8 mpg.

My Jetta TDI when fully loaded loses a couple of miles per gallon I average 36 mpg on the highway loaded.

If I had to guess, on the GC CRD I would be happy getting 25 mpg average loaded, I really don't know.

It has been 60 years since a diesel took a pole position in Formula 1.

It will be fun to see what the Porsche LMP1 looks like. Even better to watch them race the Audi's.

The rules for F1(today): "Formula One engines must be naturally aspirated, four-stroke internal combustion petrol engines with reciprocating circular pistons and a maximum of two intake and two exhaust valves per cylinder. They must be V8 engines and have a maximum displacement of 2.4 litres." In 2014 they change to a: "1.6 litre turbocharged V6 engine."

The reason they are not doing diesels is because they are too quiet. The fans like the sound of F1 cars. Bernie Ecclestone knows the F1 brand and its fans. He has tended to reject anything that changes the sound the cars make. I have been to a few USGP's; the sound makes your heart skip a beat.

Pep Boys is the only place one should trust to change the Oil in a European diesel besides the dealer. Why, because they are the only ones that sell the oil, that I know of, besides the dealer. Also, judging by the special I saw on TV they are the most honest and reasonably priced. If my Jeep dealer doesn't stock the right oil, my jeep dealer won't be doing my oil change, Pep Boys will or perhaps my old Volkswagen dealer.
Since you have raised the issue of oil, this is a big issue with the VM Motori CRD. We are still wrestling with it down under, see CRD oil on special . Fiat Chrysler Australia now require the following oil specification, "..the manufacturer recommends SAE 5W-30 synthetic low ash oil that meets the requirements of Chrysler Material Standard MS-11106, and that are approved to Fiat 9.55535-S1 or Fiat 9.55535-S3 and ACEA C3." As far as we can determine, the only oil that meets this is Pennzoil Ultra Euro L 5W-30. Mobil 1 ESP Formula 5W-30 comes very close. The dealers are using just about any 5W-30 oil so the guys have taken to either doing their own oil changes or suppling their own oil to the dealers. The problem is that Mobil 1 ESP Formula 5W-30 is hard to get and expensive and Pennzoil Ultra Euro L 5W-30 is impossible to get. Perhaps we are a bit anal about oils but it could be a warranty issue if we used something lesser. I expect things will improve once you get the diesel in the States.

The Mobil 1 ESP 5W-30. Is one of 3 oils I have seen here. The others are the "Castrol EDGE Professional - European 5W-30 LL03" and AMSoil actually has 2 different oils.

My current VW TDI is 4 years old and the oil is no more common now as when the car was new. Oil changes in the TDI were free for the first 30,000 miles. Out of warranty a large portion of the cars probably use the wrong oil. For me, my new GC Diesel uses the same exact Mobil 1 oil as my VW TDI. Actually all oils that meet the VW 507 spec meet the ACEA C3 Spec but not all ACEA C3 Oils meet the VW 507 Spec. This means that there are actually more oils I can use in my new GC CRD than my old VW TDI.

Re: Diesel People - Enlighten Me? (2014)

The oil will be a huge issue due to the unfamiliarity of Jeep dealers with the engine. I can just imagine dealers putting their regular oil in the vehicle not knowing any better...the onus will be on the owners to make sure the correct oil is used. Unfortunately less car savvy owners will have no idea about this, and if the low ash oil is not used they will see the costly premature failure of their DPF.
This is one area where (for now) it would be safer to go the VW route...they sell a lot of diesels and their dealership service departments seem to be on board with the maintenance requirements.

Isn't FAUEE a GM troll?????? Just kidding but you have to stop shooting people's puppies FAUEE
