My "new" 2008 Elantra has 11,500 miles on it. I just added a slug of
Techtron injector cleaner (12 gallon size) to a full tank of gas. How
often should this be done? Also - when I do my next oil change would it
be a good idea to shift to synthetic oil?

I add it in at the 250,000 mile mark. So far, I've not kept a car that long
so I've never had the need.

As for synthetic, it is better than dino oil, but unless you have a high
performance car and drive at high rpm and high temperatures, it is not going
to get you much, if anything. Most engines today outlast the rest of the
car with oil changes done according to the recommendations. I change at
7500 miles and can get 200,000 miles from an engine. The exception was my
83 Olds V-6 that had poor design problems.

If it makes you feel good, spend the money. IMO, it you need additives, you
really have other problems.

I run synthetics in all of my vehicles. Well, not in my K1200LT yet,
but will once the Nikasil cylinders are thoroughly broken in - which I'm
told takes about 18,000 miles. :-)

However, I pretty much agree with Ed. For normal use, the synthetics
don't buy you much. I use them for one reason - cold winters. The
starting performance at below zero temperatures is markedly superior. I
will admit that the newer 5W20 oils crank pretty well at lower temps,
but they still can't match full synthetics. Were it not for the cold
winters where I live, I'd probably just use dino oil, although the price
difference is no longer that great. Conventional oils such as Castrol
run nearly $4/qt now and I can get Mobil 1 for about $6. I remember the
day when Mobil 1 cost 4X more ($4 vs $1) as compared to a good dino oil
such as Castrol. With only a 50% cost disadvantage, I don't feel so bad
using Mobil 1.

 

I was hoping to get your take on my questions.
