Sean 83ZXT Posted February 27, 2001 Share Posted February 27, 2001 I'm getting a rebuilt Turbo engine for my '83ZXT and I'm wondering what oil I should run for the break in period? Also what weight is recommended for normal use in a Turbo motor. My engine will receive several mods later on but I want to treat it well so it will perform like a mad man! Thanx in advance. ------------------ Future 12 sec L28ET Driver Quote Link to comment Share on other sites More sharing options...
Drax240z Posted February 27, 2001 Share Posted February 27, 2001 What I've been told by my engine builder is to run CHEAP oil during break in, and change it often. I plan on running some low grade 10w-30 and changing the oil and filter about every 1000miles. Once I know my engine is broken in, its fully synthetic all the way. (especially with a turbo engine!!!) Its probably a good idea to get a strong magnet and stick it to the outside of your oil filter for your break in period as well, just to make sure none of those shavings get through. ------------------ Richard Lewis Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted February 28, 2001 Share Posted February 28, 2001 I'm not up on the turbo engines; but I agree about using a standard 10W - 30 oil for break in & change it often. Once the engine is broken in you can upgrade to a synthetic. The best synthetic I've found (My Z is a non-turbo z) was Mobil 1. When I first bought my Z I tried all three different 10W - 30 brands....the car felt a little sluggish; mind you I already gave it a full tune up & new belts, air filter. Then I switched to a synthetic brand; 1st I used Castrol, the Green Quaker brand & the Yellow brand.....they all still seemed a little better but the engine still seemed a little sluggish (It had 155,000 miles on it). Finally on the next oil change I coughed up the few extra bucks for Synth.Mobil 1 10W-30. My prob's were solved; the engine felt like it set back the odometer 50,000 miles. Never used any of the Dura Lubes, Slick 50 type additives. Just use the Mobil1 & I'm a believer in its "Slickerability" & yes Slickerability is a technical term! For additional advice you might try posting this same question on the Turbo/Supercharger forum. Kevin Quote Link to comment Share on other sites More sharing options...
Sean 83ZXT Posted February 28, 2001 Author Share Posted February 28, 2001 From what I hear Amsoil is the best oil. Does anyone know if it's better than Redline? ------------------ Future 12 sec L28ET Driver Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted February 28, 2001 Share Posted February 28, 2001 I was always told to use straight 30 weight for break in. You don't really need the viscosity changing properties of multigrade oil when breaking in an engine. Far as the various synthetic oils (as mentioned don't use for break in, to slippery and you won't seat the rings easily) I think its a personal preference which is better, they're all better than Dino oil (No haters please, thats pure science fact not fiction) and using one over another is a matter of what marketing hype you believe or your pocketbook as to which is cheaper.

Drax240z Posted February 28, 2001 Share Posted February 28, 2001 I've also heard Amsoil is great stuff. Apparently the guy that started Redline used to work for Amsoil, but couldn't duplicate things because Amsoil had the patents. Interesting. I plan on running Mobil1 10w-30 after breakin. ------------------ Richard Lewis Quote Link to comment Share on other sites More sharing options...
