yes you can synthetic oil can go in any engine
Yes.
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.
conventional. I wouldn't put synethic in it unless it has already had it in the engine. Synthetic is mostly used in high performance or new vehicles. Synthetic won't do anything for an older engine
If you have kept regular oil changes, no prep is required. Just go and put the synthetic oil in.
5w 30 semi synthetic. it takes 6 liters with a new oil filter and 5.8 without oil filter.
Put Full Synthetic 10W30
It would not be as good as all synthetic however mixing the two should not do any damage to your engine.
10w-30 either synthetic or regular Castrol for regular or Mobil 1 for synthetic
10w 40 part synthetic
Well, the best oil is either Mobile 1 or Castrol FULL SYNTHETIC OIL... 5W-30 or if you have higher miles 10W-40... PLEASE MAKE SURE YOU USE SYNTHETIC, this is what VW/Audi uses from factory on all their engines... Contrary to what many people say... YOU CAN NOT use regular oil on a car that has had Synthetic oil... it is almost like mixing water into oil... due to the synthetic oil creates a barrier in you engine to help protect it longer... if you put regular oil in an engine running Synthetic, this will cause EXTREME Engine Sludge Buildup... causing the engine to not operate correclty and costly repairs to the engine...
You can use Synthetic oil at any time. You can even mix it with regular oil. Just be sure and use the correct weight.
The best oil for a Mercedes Lorry 818 is Mobil Delvac Synthetic Gear Oil 75W-90. Is that for the engine ?
