#443 of 513 Which Additives do you use? and Why? Really work?
Jul 06, 2011 (9:00 am)
I went to this Valvoline lube express today, but so many cars, besides my $10 coupon has expired, so I just left, not experiment if oil changed and in particular oil filter changed after 3 years, my Nissan Quest 94 would solve the problem of initial start.
So far, all problems seem to be gone with all these additives, here and there, people advised. The only one left is that when it first time start, whether cold morning or hot afternoon (it is 93 degree now), it can be easily crank and start and RPM went up, but then immediate going down RPM and stall unless press the throttle, and about 2 to 3 minutes "warm up", it is perfect, and through out the day, it can be easily start and run, and engine so quiet (Thanks to Engine Restorer), and power pick up, throttle response faster (thanks to Heet, Splash and iso-heet)
Last night, I met a person at Barnes & Noble who selling some additives so ofter me to tried out the additive he claimed he used for his Nissan Maxima 2000 that keep his engine running great. I asked him how low the fuel tank he got before filling up the gas, he said, he often waited it till E (empty), then add his additive and run for another 50 miles before refill the gas.
That's amazing! That implies his gas tank may not have much "water", although his car is relatively new. Anyway, I just invite him to go get his magic bottle he wanted to sell for around $12 and claimed to be able to use for dozen times, i.e. one squeez of about 2oz for just $1 and good for a tankful of gas. So, he squeezed 2 oz into my fuel tank and assure me will feel different immediately.
It DID! My Nissan Quest 94 ran good and powerful on the way back. When I checked the bottle instructions, it says something like "oil system treatment" but did not see "remove water" or the like. His enthusiasm was just like every now and then I squeeze "Lucas Fuel Injectors Cleaner" to neighbors cars or whoever complained gas price hike, ...etc. I even squeeze some for people on the parking lot of Pep Boys. Why not? It is free!
I started getting one 5.25oz Lucas Fuel Injector cleaner by accident at Advanced Auto Parts when they had a 99 cent sale at casher. Wow! amazing! much better than STP red and white bottle I jused before. So, I decided to switch to Lucas and got the 32 oz bottle for only $10 at Walmart because that small bottle went up to $5.99 and even $5 at Walmart. So, every now and then I squeeze some into my cars and others. Later, I found the one gallon 128oz Lucas at Pep Boys for only $29, so I started buying gallon Lucas Fuel Injector Cleaner, and fill them to the 32oz bottle for easily squeeze.
From then on, every time I drive far or long trip, I would squeeze some Lucas into the fuel tank, in addition to pumping some air to tire, check all liquids, ...etc, and of course, charge battery for a few hours.
What I really want to learn is like medical doctor when you go see them with a problem, they will "prescribed" some drugs for you to go to pharmacy to pick up and take, and magically cure the problem. Instead of general advise of "taking some vitamin" ...etc.
For example, I would like to know "what additives should I pour into my van"? to cure my initial start and stall problem ? Your guess work is very welcome! I would just try and test one at a time to see which is the right one... and I want to become an expert level of "Auto Pharmacist". If I can guess or Diagnostics correctly at the very first time, I would be very famous and able to help many many people to fix their headache in a few dollars. Otherwise, a few try and error would still be much cheaper than the "guess work of auto mechanics" to replace parts here and there, every time hundreds to thousands, yet problem persist.
#444 of 513 I finally changed my oil and oil filter at Valvoline ...
Jul 19, 2011 (9:21 pm)
Somehow, they sent me another $10 coupon, so I just went changed my oil and oil filter there at Valvoline. With coupon about $22.
Then, I felt better, but I also knew that oil and oil filter has nothing to do with other problems. At least, I do not have to worry about change oil and filter for next 3 years.
What I really need to remember to do is add Engine Restorer because, ironically, after new engine oil and oil filter, the van was supposed to be running smoother, but it does not. I think the chemical in Engine Restorer in the crankcase were also flushed out.

You may have other problems, I've never heard of an oil change making a car run smoother, unless of course, it was filled with molasses.
Then again, I've been wrong many times before.

Yes, every time after I changed engine oil even not replace oil filter, I could feel engine running smoother even before I tried Engine Restorer.
This time Valvoline did not leave room for me to add Engine Restorer as months ago I added it to my crankcase after 3 year not change engine oil and filter. Maybe I have got used to the smoother and much quieter engine that Engine Restorer brought me.
Now I have to wait till engine oil shrink in the crankcase to add some Engine Restorer, may be I will just buy small bottle for 4 cylinder rather than 6 I added last time. It took about 3 to 6 months to shrink 1/4 quart when others may change oil and oil filter, I often just top off with 5w30 recommended by Nissan Quest 94 manual.
I did have other problems because the "check engine light" on, and I just adjust idle screw after start engine and idling to tune it to most smooth position. Now, it can idle well, especially when stopped at traffic light.
When I started the engine first time of the day, the engine will stall unless I push the gas pedal, and about two minutes later, it will idle normal, and through out the day.
Someone I met on the parking lot asked me when was last time I replace "fuel filter", and I said I never replace "fuel filter", should I? He said fuel may be clogged by dirty fuel filter. Is that right? May be I should change a new fuel filter ... How much would it cost?

some engine restorer additives are like molasses so beware, your engine may likely full of sludge!

I don't know how much a fuel filter would cost for your van but a good mechanic can give you an estimate and take care of it.

Which engine restorer additives would you suggest to avoid? Or, even better, which ones that you have used for your Nissan Quest and work great?
So far, I only used Engine Restorer once, and it seemed to give me immediately great effects of the following:
1. As soon as I start the engine, I notice the engine quiet down, and it quiet more each day for the following few days I drove till very very quiet.
2. I noticed the smell used to came out of under hood when engine start were all gone, instead, it smelled very good, like the smell of early morning in the forest.
3. No more smoke came out of the tail pipe, in fact, it came out some water drips when it starts and warm up.
4. The engine oil turned from dark brown into very clear like new engine oil.
5. The millage increased unexpected.
Basically, what they testified in their website in line with my own experience with Engine Restorer. And, every time I revisit their FAQ section, I understand it better with more insights.
For example, I have set up a schedule to wait till my newly changed engine oil to shrink 1/2 quart to add Engine Restorer of 4 cylinder (rather than 6 cylinder) instead of use Engine Restorer every time I changed engine oil and filter (because I only would change engine oil and oil filter every 3 years, other time, I would just top off the 5w30 engine oil as recommended by Nissan Quest manual), and as I top off Engine Restorer rather than 5w30 from now on, I would have more of it than just bigger can for 6 cylinder. This also came from my own experience on adding Engine Restorer 3 year after previous engine oil and filter changed. I feel it does not need to be replace Engine Restorer every time change oil and oil filter.
If from most auto mechanics "myth" of "3,000 miles or 3 month" change oil and oil filter and Engine Restores' suggestion of add it every time change engine oil. It would be too much waste. However, if add it every 3 year when I changed oil and oil filter, it may be too long (yet to be seen, and I will find out). The thing is that I do not change oil and oil filter myself, instead, I drove thru to get them changed and replaced by places like Lube Express or Valvoline Express, so it is hard for me to bring a can of Engine Restorer to ask them to add for me.
So the perfect timing to add Engine Restorer may be wait 3 to 6 months when engine oil shrink dark brown to about 1/2 quart to top off with 4 cylinder Engine Restorer. One thing that bothers me is that their design is like coke, you either open and use the whole can or not open or waste. Ideally, if it can be squeeze into crankcase a few oz every so often or whenever needed like Lucas fuel injector cleaner that I squeeze into gas tank every time I going to go long trip.
Another thing I need to find out is to see if there is gallon container of Engine Restorer. e.g. the 5.25oz Lucas fuel injector cost about $5 at Walmart, where as 32oz, about 6 times more, only cost $10, and I found 128oz the gallon size (4 times more) of Lucas fuel injector at Pep Boy only $29, so I use the gallon size now. Every time I bought the gallon, I filled the two 32oz bottles, and every so often when I go long trip, I just squeeze a few oz into fuel tank depending on how much gas left, NOT need to worry about fill the tank right after.
#451 of 513 How to Replace Fuel Filter for Nissan Quest 94 ?
Jul 20, 2011 (9:16 pm)
Ok, here I found a video clip that shows how to replace fuel filter for Nissan Maxima which is very informational because Nissan Maxima 94 is the same engine as Nissan Quest 94, and I have checked the layout of under hood of both cars; they look so similar.
I also went talk to STS who gave me an estimate of the job was $120 plus tax, may be more, depending on the parts.
Somehow, I found this $3.66 fuel filter that seems to be the correct price because a fuel filter is no more complicated than an oil filter with similar size.

I just went back and check the statement given by Valvoline Lube Express and found out that they only add 4.2 quarts of new engine oil to my Nissan Quest 94, whereas it was supposed to be 5 quarts.
But, when I checked the oil dipstick, it shows full of the engine oil and very clean and clear. Where was the 0.8 quarts gone?
By the way, as time goes, the engine running much smoother with newly change 5w30 engine oil and Valvoline oil filter.
