In your everyday car have you ever switched from Conventional motor oil 2 synthetic & noticed a big difference

Like have you noticed the engine ran smoother after changing to synthetic. I don't care about brand name.....just switching from conventional mineral oil to synthetic?In your everyday car have you ever switched from Conventional motor oil 2 synthetic %26amp; noticed a big difference
No I can't say that I have but, I read an article a few years back in Car Craft. They took a car and put all syn fluids in. Motor, trans, rear end. Then they ran it on the dyno. They did a baseline with the conventional fluids then tested it with the syn fluids. They actually gained a few HP. But nothing major.In your everyday car have you ever switched from Conventional motor oil 2 synthetic %26amp; noticed a big difference
I use nothing but synteck in every engine i have. I was a jet engine mechanic and we were first to use synteck oil. it does not breakdown or carbon up your engine. I would nor use anything else. i have not noticed that anything runs better using synteck oil but you do not have to change your oil as often. We would not change oil in the jets just clean the strainer every 60 hours. I change my oil once a year now.
I don't think there is anything that you can visibly see or hear when you make the change. You may notice that your vehicle will run cooler and may see an increase in MPG, but you won't see a drop in your engine RPMs as stated by another user. That's impossible...





You will also see an increase in the ';life'; of the synthetic oil. Thereby, increasing the interval between changes, resulting in financial savings. Plus, the synthetics have a great guarantee.
Well let say this that the cost is the real difference.The really the synthetic oil life is longer than the regular motor oil. Regular motor oil need to be changing around every 3000 to 4000 miles and synthetic need changing around 10000 to 14000 miles the life of is longer and better on the engine parts.The synthenic oil will make your engine run just a little cooler and add life the engine
I've experimented with this numerous times going to synthetic and even back to conventional and then back to synthetic. I can't tell a difference at all in how the engine runs. I do believe synthetics are better oils and are practical if you extend the oil change intervals. Otherwise, it is difficult to justify the added expense of synthetics. If you drive your car 100K miles over its life and you change every 3000 miles you will do 33 oil changes. If you use synthetics and move that up to 6000K miles perhaps it makes sense and then you save time as well plus pollute less with oil disposal. The negative to less frequent oil changes is that you have fewer opportunites to see other potential maintenance items such as corroded battery cables, cracked FWD axle boots or swollen water hoses if anyone pays attention to those items when doing the oil changes. With cars as good as they are today, longer change intervals make some sense. I use them on my personal cars.
Hey bungee! you can actually tell it dropped 75 rpm`s. You must have the only gauge in the area capable of that fine a reading. Did your speedo also read in feet per second? By the way. Mineral oil would make a big difference. It wouldn`t run long.
nothing you could tell from sound unless your realy bad off and youve ran your car low on oil before but if you got the money i suggest do it it helps alot not to mention synthetic wont build up like regular motar oil will
I did on my honda. on cruise control on the same road my engine r p m's dropped about 75 revs with mobil one at the identical set speed
