if your grout had not been seal then it will be hard to clean and if you clean with acid the grout will be change color.
You need to use a stripper. Home depot has great tile cleaners and strippers. You must reseal the tile and grout after use. It is a big job, but it works. When we moved in our house the tile was white with black grout. Moved the fridge to find that the grout was lt. grey. Used this method and the grout came clean. Good luck
To apply boiled linseed oil on Saltillo Mexican tile, first ensure the surface is clean and dry. Use a clean, lint-free cloth or a brush to apply a thin, even coat of the oil, working it into the tile and grout. Allow the oil to penetrate for about 15-20 minutes, then wipe off any excess. Let the tile cure for at least 24 hours before walking on it or applying additional coats, if desired.
You remove oil based paint on tile floors by using a strong detergent mixed with water and a soft cloth
First, clean the tile and grout with a harsh cleanser such as T.S.P. Next, apply a bonding primer to the tile with a brush or roller. It can be oil-based or water-based, and you can thin it slightly if needed to get a smooth, even coating. Once the primer is dry, apply your alkyd (oil-based) paint over the primer with brush or roller.
Remove the oil pan from the engine and clean it with kerosene.
To maintain a clean oil engine for best performance and durability, regularly change the oil and oil filter as recommended by the manufacturer, use high-quality oil suitable for your engine, keep the engine clean, and monitor oil levels and quality regularly.

Oil contains detergents that clean your engine and suspend soot, deposits, & dirt in the oil. The air and oil filters remove most of the larger particles but some get in the engine and stay suspended in the oil which causes it to turn black. Oil is not only a lubricant and helps cool the engine, but it also keeps the engine clean.
I recommend consulting the flooring manufacturer, however, my experience suggests that the application you describe is an acceptable risk. Adhesion of floor tile to grout is more important than the grout's adhesion to the painted concrete substrate. Uniform stability is very important, and you have that with your painted concrete slab. When I had my tile done, the company used a primer to rough up the smooth surface.
You might have to much oil in the engine. Check oil. Clean spark plugs. (remove and use sand paper to clean)
Not far, anyway. The engine flush is not engine oil ... its only purpose is to, hopefully, clean the inside of the engine areas. That's why it's called "Engine Flush" and not "Engine Oil". Get it out and put the new oil in soon.
