guys , what's the difference between liqui moly toptec ? synthoil ? molygen ? they are all fully synthetic oil , right ? I'm looking for fully synthetic oil now for my persona ... Or any brand suggestion for fully synthetic oil ? I have been using shell helix semi synthetic all this while , i can feel the engine sound is quite rough
Engine sound rough, is inherent in the engine and its parts, nothing to do with the oil.Since, the Persona is not a high performance car, right spec Mineral oil will do. Any oil with XXw-40 will do. Change it according to Proton's recommended interval, every 6 months or 10k km.
If you want better protection, for the occasional, sprint, semi synthetics would be better.
Synthetic oil is overkill for a Proton. But, if you have a lot of money or if company is paying for maintenance, synthetics.
