yes
No, old oil can use synthetic engines
Lucas also makes a synthetic engine oil additive.. Yes.
If the engine is original, use standard oil. If the engine is new or has had a full rebuild, using synthetic oil will result in a longer life for the engine.
Yes you can use a synthetic blend or 100% synthetic.
No, I would not recommend using synthetic in an engine this old. Use a good 10w40 conventional oil.
if it's a turbo engine you should only use synthetic oil only!! if it's a non-turbo engine a conven. oil will do.
Yes. You can use synthetic oil in a 1996 Ford.
I use synthetic oil in my 2002 PT Cruiser, and it runs great! Synthetic costs a little more, but it actually better for your engine.
If your engine leaks oil, no you should not use synthetic oil because it will clean sludge and can make the leak worse. If your engine does not leak oil, I would highly recomend using synthetic oil(Pennzoil Ultra 10W30 from Walmart is a good and pretty cheap choice). As long as your engine does not leak oil using synthetic oil is a great choice regardless of how old it is.
No problem at all.Tip: Always use Fully Synthetic engine oil in your car/motorcycle.
Not if the engine is original and has more than 100,000 km on it. In that case, just use a high viscosity 20W-50 standard oil. Synthetic oil is expensive and is of no benefit in an old engine. If the engine has had a full, quality re- biuld, then use synthetic oil, and you'll get a longer life from the engine.
