just a quick question b4 I fire her up, Should I put 20w 50 in my new motor for the break in process? or go with 10w 40 or 10w 30? its a turbo II . I just am not sure if heavier oil will effect it any with the break in procerss? thanks

 

Good question. Just of my own reasoning I would assume it would make the break-in period longer, but you would get a better break-in. Hopefully someone else will step up with facts though.

 

10-30 for 500 miles, then change oil and filter, and at that time put in the oil of your choice .

 

ok since this topic came up read the first paragraph. what do you think the validity to that is?

Try 10W30 for the first 500-1000 miles. Then change to 20W50

 

Won't it just make the break-in quicker though? If I used all 20-50 and just took it lighter wouldn't I achieve a better break-in and higher compression?


My plan has been to not go over 4000rpms and use varied RPMs under that for 1500miles with no boost as well. Change the oil/filter at 100/250/500/1000/1500/3000. I am not concerned about money or time/mileage and just want to get the best compression out of this engine as I possibly can. Does my plan seem good or no. And is there a good reason to use 10-30? I'm in FL and its hot as hell so I usually use 20-50 in all my cars year round.

 

I can only tell you what I'm doing...with my fresh break In (very soon), I will be using 20W-50. However, I will be using the lesser quality Oil, for lack of a better term, to speed up the break in process. Post 1000km's, I will quickly revert to Castrol's 20W-50 and stick with that.

With new Rotor & Stationary Gear Bearings - this will be all the more complimentary In "breaking" In the fresh Engine - and It's Bearings.
