New member, first post. I have been using Castrol GTX 20w50 with the Lucas Break-in Oil Additive with no ill effects but was wondering if I should be using something else. I am interested in any recommendations.
Here is my information:
1. What kind of vehicle you have: {1984 n/a Porsche 944 (105k miles)}
2. What your owner's manual says -- not just viscosity, but certifications (look for acronyms like API SM, ILSAC GF-4, etc.) and change intervals as well: {I use 20w50: From the owners manual:
Use only branded HD oils which satisfy the APl classification APl SE or SF for gasoline engines.}
3. Where you live: {Vermont}
4. How you drive (easy? hard? fast? slow?): {Easy but fast (infrequent hard/high rev shifting but fast in 4th or 5th)}
5. What your daily drive is like (short trips? long trips? city? highway?): {Not a daily driver, but typically 3,000 miles per year. Distance of trips vary from 50-200 miles. Mainly highway mileage with some spirited jaunts around the back roads
}
6. Whether your car has any known problems: {No issues.}
If you have any preferences -- synthetic vs. conventional, store-bought vs. ordered online, how long you'd like to go between oil changes, etc: {Conventional oil is preferred, store bought if possible. Oil/Filter is changed every 3,000 miles.}
Thanks very much in advance for any responses.
