what would happen if i used non-synth oil? i'll change the oil religously. every 1500 miles, on the dot.

 

Your car would start on fire.

=P

It'll be fine. Synthetic just reacts better to prolonged abuse.

 

1,500 miles between oil change? that oil is hardly used..........

 

I have always heard that synthetics are better for turbo cars because the oil is more resistant to gunking up/cooking in turbos' bearings. Thats why I use synthetic oil

 

i've heard that it's actually better to use non synthetic on turbo motors. I heard that the synthetic thins out while our motors need it to stay a little thicker for the protection. I just use 5W30 castrol GTX and not having a problem. Hey if John Force uses it, so can I.

 

I've put around 40,000 miles on my two turbocharged Honda's. I only use regular old Castrol GTX non synthetic. Change it every 3000-3500 miles. Never had a problem at all, never burned a drop etc...

i know more engine builders that say "DO NOT USE SYNTHETIC" than say "use synthetic." personally, i use 10w-30 castrol gtx.

 

I read about a CBR900RR that had 100,000 miles put on it, and all they did was change the oil every 3000 miles (Castrol GTX). Made me switch too.

 

Well Maybee I should switch. I am could save a bit of $$ using conventional oil. I just always though that synthetic had a better abiltity to not break down at higher tempes then conventional.

 

it does

 

If you change your oil every 3K then thermal breakdown should not be an issue with a good quality motor oil...
