Question:
Solutions for an Engine that Burns Oil
I'm wondering what the best oil choice is for a 1980 Chevrolet Monza (L4 2.5 Liter 2BBL engine) approaching 57,000 miles. It's running great but burns quite a bit of oil. I've been using Pennzoil high mileage for almost two years (either 10W-30 or 10W-40). It also has Rislone's Compression Repair with Ring Seal currently in with the oil (just for the last couple months) to try to cut down on the consumption, but I'm not sure if it's helping very much and I don't know if I should put more of that back in with the next oil change. Anyway I want to try a new oil. This site says that 5W-30 is the viscosity recommended by my vehicle manufacturer, but is that really the best one to use with everything taken into consideration? and is switching from a high mileage oil to a conventional one at this point also a good idea? Your advice will be appreciated. Thank you.

Answer:
Based on your description of high levels of oil consumption, we recommend you use Mobil 1 15W-50. In the winter you might want to switch to Mobil 1 High Mileage 10W-40.
