Well that is the normal procedure for running in a new engine anyone else who knows will tell you the same thing. I did this on both of my forged motors as its what my engine builder advised me to do. I would also check valve clearances after 1000 miles.
this is normal dude dont worry. On a fresh engine i recommend using mineral oil for the 1st 1000 miles. 1st oil change at 50 miles second oil change at 200 miles 3rd oil change at 500 miles 4th oil change at 700 miles 5th oil change at 1000 miles. After 1000 miles use the oil of your choice. Hope this helps.
I see your silver GT every morning near hinckley road area,
My black V is off the road untill the weather gets better, I am currently using my silver GT for the winter.
I paid £750 recently for an almost stock gt with approx 75k on the clock. I have been offered £1500 already and in not even looking to sell it just yet. I know the car will be worth alot more after i have given it a good clean up.
if its pre 93 then no emission test is required anything after 1993 will be tested for emissions . Your best bet is to find a friendly mot tester. I know some charge a little extra to pass failed tests but this is illegal.
