I'd like to put in a synthetic oil this weekend. I'd like to see if the forum has some recommendations.
1. What kind of vehicle you have
2004 Dodge RAM 1500 with a V-8 5.7L HEMI
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
5W-30 at 3,000 miles
3. Where you live
Sacramento, CA where it gets down to the low 30's in the winter. Truck is parked outside.
4. How you drive (easy? hard? fast? slow?)
Fairly easy, occasionally I'll hit the gas. I only put on about 6,000 miles a year.
5. What your daily drive is like (short trips? long trips? city? highway?)
The truck is only used on weekends for work with a combination of city and highway driving. Truck has a towing capacity of 10,000 lbs., I tow a small cargo trailer under 2,000 lbs. loaded.
6. Whether your car has any known problems
Nothing significant
