For your average N/A near stock Hyundai motor. You guys wanan use the dino oil. The synthetic is not gonna help you. Unless you live in the high rpm range alot.

If you are now turboing and/or supercharging,you have to go with a synthetic oil.

Yes, If your car has more then 10k miles on it, you beed to run a flush before switching to a synthetic from dino oil.

Brands dont effect oil quality to much, its all preference. just nothing to cheap and nothing to expensive.

One thing! Once you start using syntheic you can never go back to normal oil! word of warning!

 

I've been using mobile 1 synthetic for the life of my car, and I love it. Another good oil to use is "greased lightning," it has a very high amount of teflon, which has the worlds best viscosity. Yes, I spend 4.27/quart, and yes I spend 10 dollars on a K&N oil filter, why, because when I use normal filters, my car is sluggish.

 

How can you love a motor oil? Honestly how can you tell a difference in engine performance between regular oil and synth. unless you perform some sort of monitor study over a determined amount of time, taking statistics on items such as gas mileage, parts wear, etc. I have Castrol in my car now. If I changed out to synth at my next change what difference would I see/feel/notice?

Plain and simple. All oils basically do the same thing regardless of type. Changing your oil at regular intervals coupled with tune-ups and routine maintenance will make your car last 100k miles plus. IMO.

I gathered this info from the link above about Teflon in motor oil....

DuPont's Fluoropolymers Division Product Specialist, J.F. Imbalzano said, "Teflon is not useful as an ingredient in oil additives or oils used for internal combustion engines."

This conclusion seems to be borne out by tests on oil additives containing PTFE conducted by the NASA Lewis Research Center, which said in their report, In the types of bearing surface contact we have looked at, we have seen no benefit. In some cases we have seen detrimental effect. The solids in the oil tend to accumulate at inlets and act as a dam, which simply blocks the oil from entering. Instead of helping, it is actually depriving parts of lubricant.

The problem with putting PTFE in your oil, as explained to us by several industry experts, is that PTFE is a solid. The additive makers claim this solid coats the moving parts in an engine (though that is far from being scientifically proven).

ok first of all, walmart is probably the LAST place i'd take my car. And synthetic oils are awesome. I've been using them for years, and i love it. I'd rather spend the extra $1 or 2 a quart and get some decent oil rather then have my engine overhauled in a few years.

Also if your going to be racing or running high-rev's, sythetics don't break down as easily or froth like regular oil.

anyway, synthetic is good if your running your engine hard. apart from that, regular is fine

 

OK.. with high boosted or oil burning engines

Regular oil... when burned.. leaves grudge and slush and crap like that behind
thats why we use engine flush...

Synthetic... when burned, it just evaporates

On a regular engine... no reason why you should get synthetic

On my nitrous tibby i use regular oil
On random's turbo tibby, he uses synthetic

 

Last vehicle:

1995 Chevy S-10 Regular Cab.

Oil used: Castrol (the regular stuff).

Miles when traded: 98,700 (owned it 4 years).

Regular oil changes every 3k miles.

No major engine repairs. wink

 

On my 99 Elantra I started using valvoline durablend 10W/30 at around 30,000 miles. When I started the engine cold it would tick slightly and go away after warm. I didn't think to much of this due to the mileage. Now I have my 02 Elantra and I just started to use Valvoline durablend 10W/30 at 5000 miles. This engine did the same thing. I have gone back to regular 10W/30 and do not get the ticking.

If you don't get a slight tick at cold start up what oil (brand and grade) are you using?

 

My 93 Jimmy with the 4.3vortec is at 152,000 miles with normal oil every 3000 miles. the thing still runs like new.
