Hey all


I have a question for yall what is the difference of synth mobil 1 5w40 vs synth Mobil 1 5w50. For the ones that have used both oil please comment & let me which one is better for the engine. I used synth 5w40 for my car but I just saw the synth 5w50 with the label saying more performance, so I thought maybe this new oil is more better for the engine. So let me know anything.

 

Which engine? The approved Mobil 1 for the 1.8T is 0W 40

 

umm i just put mobil 1 syn 5W-40 in...is that ok?

 

Hey

The car is 2000 A4 1.8T 62k the engine size is ATW. so whats the difference between the two synth oil

 

The 0W40 meets the newest Audi standards, the 5W 40 Mobil 1 doesn't. Chemically, I don't know the difference. No harm will happen if you have used the 5W 40..after all it is good oil
