Am looking for a prizm, and i found that there are 2 engines.. which one gives better mpg, more hp? is more reliable? (any of those burns oil like the next gen engine?
4A-FE with 5-speed manual gives the best mileage
7A-FE has more power.
Both are equally reliable.
Both have tendencies to burn oil, as does the 1ZZ-FE.

that also called my attention.. according to fueleconomy.org the 1.8 5 speeds gives an extra milles over the 1.6... is that a mistake?
No.Not a mistake.Bigger engine does not necesarily mean lower mpg.
7th generation engines should not be compared with 8th. in oil burning. Average maintained 4AFE/7AFE does not burn oil. An abused one might.
I have a 1994 Geo Prizm with 1.8lt engine and 4 sp. auto transmission. In Wisconsin winters I get 28mpg (75% highway-25%city driving) and in summer I get 30-33 mpg. I might have a bad thermostat, and overdue spark plug replacement. After these are replaced I am hoping to get 35mpg.
The most powerful 7th generation Prizm/Corolla is 1994 1.8lt ones. 115hp.They lowered the hp for the same engines a year after that for emissions purposes.

True, but if I'm not mistaken, the 95-97 1.8 litres had a little more torque and the power arrived sooner, Also, again if I'm not mistaken, there were changes to those same 95-97 1.8 litres to address the oil burning/use that was a complaint with the 93-94 versions.

It is the first time I hear about this oil burning complaints for these cars.I did not know they were oil burners.
Between 10,000 miles OCIs I used to lose about half a quart, and mostly through the valve cover gasket (a bad replacement job by a shop). If you call it oil burning... The odometer is just a tad below 160,000 miles.

What changes have they done to address those oil burning complaints?
If you do a google search you'll find more info. The oil burning issue seemed to be the worst on the 93-94 models, and when the 98-2002 models (new engine) from what I gathered. I believe Toyota tried to fix this issue with varying success. It seems the 7A-FE was the hardest hit with this issue.
some say that they fixed the oil burning for the 95-97 7afe, others say they still have the same problem. It happens at high mileage. It will happen to every one eventually before the engine blows. It has happened to me twice now. And since the 8th gen motor also has oil consumption issues, makes me believe that the 95-97 7afe will also have it. Why would Toyota solve their oil consumption issue and then release a new motor with the problem again?
I've only put 6500 miles on my 95 Prizm, changed the oil at 3,000 mile intervals the first two times. I'm going every 5,000 miles here forward, next change is at 200,000 miles. I've not had to add any oil between changes and I know I have a slight leak at the front of the engine, so it cant' be burning much. Hoping to fix the front leak when I replace the timing belt around 225,000 miles if all continues to go well.

...so you're saying, if someone buys these Corollas don't keep them too long and/or attain high mileage on them, because the engine will eventually need to be replaced? One of the reasons the oil issue would be on the new motor, is that it is a new motor, with a timing chain, VVT technology and a starting out, rubber oil hose feeding oil to the VVT system.
yes, avoid high-mileage cars is a good general rule, but especially with this engine. It also sucks because if your engine blows (like my first did), the put in a used 7afe and of course it had the same problem, so it blew the same way as well

... Thank you. Is this only for the early 7A-FEs or all of them? Especially in wagon models, this engine is standard. It would be a shame to not be able to consider a Corolla wagon or a Corolla/Prizm sedan with this engine if there are going to be problems later on.
I have had no problems with my 7afe engine or transmission so far.The car has almost 160K miles. My oil change intervals are 6 months or 8-10K miles with Castrol Syntec 0W-30 (German-made) or M1 0W-40. Engine and transmission are in great shape however I have this fuel line leak problem now that makes me sad. It would be a shame if I end up having to junk the car for rusted fuel lines...
4AFE and 7AFE engines are listed in 10 best engine lists. They are one of the most reliable/problem free engines. Problem engines are 1998-2002 model year engines, especially the vvt-i types. Heavy oil burning and sludge. Nothing like that for 4afe and 7afe engines. Let's not distribute false information.
