Q: Do oil and fuel additives really help your car run better?: i would say they MAY. in my 200 sx (basically a '96 sentra 4 cyl, 5 sp) i drove 300 miles in usa then added SOME gas additive in monterrey mexico and filled up on pemex. i would drive to 275 at the half-tank mark, (which i am acutely in tune with-as today, i hit 255 miles at the 1/2 and will get 502 miles and need 12.5 gals if i continue my work route) in usa it is difficult to hit 250 with highway driving at 70. last 3 years i drive 50-55 to get 40-44. on my return trip i used bardahl from mexico and in usa, on exxon gas, STILL COULD NOT get much past 250 at the 1/2. was it pemex or was it the additive?!? i used super nova and exxon supreme all the time. it is the mexican gas formula or the additive. next trip, i wil eliminate the additives and see! as far as oil additives, i don't think they are necessary. i am using a sm grade 10w40 in texas, castrol. any modern oil is sm, weight depends on your climate, but in russia i use 5w 40 half-synthetic lukoil. in texas, many swear by straight 30 weight, but not me. the additives are already in the oil and adding more is not necessary.

Q: I prefer DIY, I heard that Angel has a 20 minutes will be able to blow up the fritters of the product, in OKorder near Chongwenmen how to sell it?: An Qi quick combination of fritters leachant formula in the use of various raw materials are in line with national GB2760-2017 requirements, without aluminum alum, the use of risk-free. The use of the leavening agent, no need to add alum, alkali, from the kneading to the production of molding, just 20 minutes, very fast and convenient.

Q: My saturn has been losing oil lately, and I recently purchased lucas oil stabilizer because I heard it slows down oil consumption. Will I need to put more of this stuff in every time I get my oil changed? or will this first usage of it be enough for the vehicle? thanks: Well, here I go again.Now I'm convinced, there is a Santa Claus and indeed a miracle-in-a-can cause somebody said blah, blah.Don't fool yourself, engine oil additives and restoratives are an infamous scam and generally do more harm than anything else. Sooner or later what is really wrong with your engine will reach out and bite you on the A**. Google Federal Trade Commission and Dura Lube for example, pretty much sums it all up. Although, the little Lucas demo toy down at Autozone with the plastic gears you can spin around sure is fun and it's just like a car engine.Right?

Q: If you can give the easiest to understand explanation, will be appreciated: Additive Vs Subtractive Color

Q: What is your opinion on Food Additives?: ALL food additives (healthy or not) should be OPTIONAL. Let the buyer of the food decide what is or is not to be added. Why force everyone to buy a preserved or canned or frozen food with all the stuff already in it that many may NOT want, or even know is in there ? Same is true of fluoridated water. DON'T wreck the plumbing and pipes of cities by FORCING people to drink this water. Fluoride is a HIGHLY TOXIC waste product of the aluminum industry, and does LITTLE good for most people except 1-2 year olds as their teeth develop. Makes EVERYONE sick, slowly but surely. Instead, offer at a HUGELY REDUCED COST--**FREE** fluoride pills to anyone that wants them.

Q: the question was .Find the product (x+10) and its additive inverse.(:: I believe the product of anything X's its inverse1

Q: Are there any additives in the peanut oil of various brands in the supermarket? Is there something like fragrance? Feeling with their own peanut oil taste is not the same, their bar is very mellow fragrance.: Peanut oil light yellow transparent, bright color, smell fragrance, taste delicious, is a relatively easy to digest edible oil. Peanut oil contains more than 80% of unsaturated fatty acids (including oleic acid 41.2%, linoleic acid 37.6%). It also contains 19.9% of saturated fatty acids such as palmitic acid, stearic acid and arachidic acid. Peanut oil fatty acid composition is relatively good, easy to digest and absorb the body.

Q: what are diesel fuel additives and how they work?: diesel fuel additives are mainly for getting water out of the fuel because water is very bad for diesel injectors.

Q: What is the additive inverse of 4i?: An additive inverse is what you can add to a number in order to produce 0 (i.e., for it not to affect an equation if you were to add it and its inverse). 4i + x 0 x -4i
