Howdy, My goal here is to have an baseline of oil burning and to attempt to reduce that oil burning by utilizing various established methods. Test Case: 1998 Saturn SC2 rare "Red Hot". Bought with 157k miles, now has 159k miles. Amount of Oil Burning: A consistent 1/2 Quart per 200-250 miles. Current Oil Being Used: Pennzoil Yellow Bottle (PYB) 5w-30 + 1 bottle of LubeGard Bio-Tech. Background: I bought this car last Fall and the owners did not know it was a rare car. It was low on oil when I bought it and had some darkened areas on the dipstick, so I knew it didn't get the best of care. That's OK, because I got the car VERY CHEAP. It had LOTS of serviceable items already replaced. Although this is a "Saturn", it is a very rare "Red Hot" package from the factory with only 657 made in 1998. I am determined to keep this car as long as possible & in the best condition as possible. It will not see road salt & will be in garage stored during the Winter. Starting the experiment: There's 2,000 miles on the Oil. I added 14 Oz. of "Kreen" to the oil yesterday (emptied what was left in the can). I have 1 more unopened can of Kreen. Am running it about 200 miles today. Things to Determine: - How long should the Kreen be in the oil to effectively give it it's due? - Kreen's label says you can add a pint to the oil every 1000 miles. Should I do that or use it "one time only" then on to another variable? Next Steps after Kreen: Don't want to do a Piston Soak, so I am trying other methods first. I was initially thinking of running Mobil 1 5w-40 Turbo Diesel Truck (TDT), (I have 30 Qts. of it...) as it has a HEAVY Additive Pack and heard it effectively reduced the oil burning in Saturns. BUT, it's high in viscosity, so I was thinking of running 2 Qts. of Pennzoil Ultra (PU) to get the viscosity down, + 2.5 Qts. M1 TDT next. Which way should I try first? Let me know your thoughts/successes/failures and we'll go from there! Turk.
