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.
5w30 pennzoil ultra or mobil 1 5w30 -use only synthetic oil
pennzoil platanium full synthetic AMSOIL
Yeah you can use that, it will be fine, Mercedes recommends 5w-40 full synthetic oil though, either mobil I or pennzoil synthetic
I change my own oil and pay $24 for the Pennzoil Synthetic oil and $5 for the Purolator filter for a total of $29.
yes you can synthetic oil can go in any engine
Mobil 1 pure synthetic. Answer 2: Any 5w30 synthetic oil that meets the GM oil requirement. Mobil 1 and Pennzoil Platnum (iirc) are ones that do, and I believe there are a few more.
Lucas also makes a synthetic engine oil additive.. Yes.
Yes, you can. It is even sold as a Synthetic Blend.
No, old oil can use synthetic engines
0w40 if below 0 degrees and 5w30 for all temp. mobile one DOES NOT HAVE TO BE MOBILE ONE BRAND, AS LONG AS IT IS "FULLY SYNTHETIC" CASTROL, PENNZOIL, ETC
Use SAE 5w30 full synthetic. 4.2 quarts with oil/filter change. Use any major brand of your choice, but I recommend Pennzoil Platinum Full Synthetic.
