A friend of mine is wondering if he should run synthetic in his turboed civic. It doesnt have more then 10,000 miles on it and he is running a gt35r turbo. Is there any pros to running synthetic in a turboed car and what are the cons...right now hes running castrol gtx 10w-40! Any help would be great!

 

I tried it out and its just too thin in my opinion. In mine after only 500 miles, it looked like water when it came out. (no headgasket isnt blown )

I switched to Valvoline Racing 20W50 seems to be much better after oil changes

 

do a search this is asked all the times.

But to answer your question synthetic usually burns more oil. I would keep running castrol gtx.

 

i beg to differ. on a new car running turbo i recommend Mobil 1 syntec 10w-40. mobil 1 is one of the few brands to make a fully synthetic oil (not blended). new cars are designed to run synthetic and as long as you run 10w instead of 5w, you should be fine. my 98 civic has 87k miles on it and burns NO oil nor does it look like water.

Well on my last civic with a built motor. When I switched over to mobil 1 I had a hell of a lot more blow by and it burned oil like it was nothing. I switched back to gtx and problems went away.

 

you should not run anything but synthetic unless you have a water cooled bearing section. Synthetic has a lot higher of a breakdown temp which is very important for the life of you turbo, as the bearings won`t coke up nearly as easily with synthetic

 

Wow so this really got us no where... So is it safe to run with his ball bearing turbo? What about a turbo with a thrust bearing instead? So Should he be running synthetic or stick to castrol?

 

almost everyone I know runs normal oil not synthetic and has yet to have a problem with their turbo.

 

I hated synth. when i was n/a.....i hate synth. now

On the other hand, I don't think I know anyone down here who runs conventional oil..

Nothing but Mobil 1 here.

 

i use regular old castrol gtx 5w30 in my em1 thats turbocharged no problems yet

 

i use mobil 1 5w30, works for me, no problems as of yet but only about 4500mi turboed.

 

mobil1 10w30

 

I use Amsoil 0w-30 and no problems here

 

I must be crazy I run Mobil 1 5-50

 

A 5w30 mineral and a 5w30 synthetic are both subject to the same viscosity tests. So, they both have to fall within a certain range to be marked 5w30.

Saying that a synthetic is "thinner" is incorrect.

 

Amsoil turbo formulated 10W30

 

Basically users descretion because it seems everyone runs what they want lol... Just wanted to see for him because he wanted to know if synthetic would make a difference.

 

lots of different opinions lol

 

Can we get a straight answer on this? And why one is better than the other.

Lots of good info.

 

I have been using Royal Purple for the past year or so. I usually ran valvoline and hated synthetic, but then i saw some real life tests on valvoline, castrol, mobil syn, and RP. The RP just stuck to the metal as it got hotter and hotter while all of the other started burning and eventually hardened on to the metal. After 24 straight hrs of testing and heating up you could run you finger across the metal pan with RP in it and it still had a smooth oil layer that clung to it. I also noticed an increase in gas mileage when switching as well. IMO its the most advanced oil you can get and alot of people have proved that.

 

Ahhh cant get off subject with RP...

The question still stands: Is synthetic oil better to run in a turboed car then conventional oil? PROS & CONS

 

I use full synthetic in my car...

I have read many places that say you should only run synthetic with a turbo charged car...

Like was stated before, synthetic oil his a higher breakdown point and can better withstand the added heat of a turbo system...

I have heard many times that conventional oil breaks down too fast if it's being run through a super hot turbo...

Anyways, I run synthetic and it seems to be working fine... I guess I'll switch if there is a convincing enough argument for conventional oil..
