i DID A search to no prevail. I remember about a year or so ago reading about an oil that was said to cause a lot of turbos to fail/seize up.

IIRC it was either AMSOIL or RoyalPurple.

Anyone remember?

Thank you for any help.

Royal Purple.

 

Ive ran amsoil with zero problems, ive seen tests showing royal purple is alot of hype when compared to amsoil, but its never done me wrong so its hard to be skeptical.

 

I've ran conventional mobile 10w-30w for 3 years boosted no problems making 250hp b16.

 

which has nothing to do with this thread. Thanks

 

ive been using royal purple on my boosted DC5 for over a year now with no problems. the only thing i did need to install was an oil pressure restrictor because the bearings are only rated to 60 psi and my oil pressure gauge was reading over 90 psi at times, and i was getting a little blow-by. but not any more.

K20A2 eibach double valve springs / tit retainers, arp head studs, copper head gasket, precision t3/t4 turbo .63ar, tial 38mm, revhard cast manifold, walbro 255lph, aem fuel rail and pulleys, treadstone fmic, custom 3" down pipe and 2.5" ic pipes.

8psi on 93 oct=315whp 205wtq
10psi on 109 oct=346whp 225wtq

 

The only bad oil for a honda is redline; and that's only in the tranny. It eats up the carrier baskets in the bearings.

As for the motor: I have run nothing but Mobil1 pure;

the engine stays 100% clean, no buildups/deposits; oil has same texture/viscosity "feel" as new oil when changing after ~5k miles

I would say this though: never touch a can of "Engine restore"; blue ****, silver can; like a beer for your car. That **** will make your rod bearings spin; if not soon, it will.

Those fail no matter what oil is used.

yep... i use redline in my tranny, no problems at all

if you have oil problems the turbo is going to be the last thing you are worried about. if it wont work in a turbo, it wont work in your engine.
