Hello All, I have been on a mission to slow down/stop(not likely) the oil burning on my 1999 Saturn SL1. When I had gotten the car it had 112k Miles about a year and a half ago, it also had a bad thermostat(no telling how long the engine had been running cold, I think this is probably where the consumption started) Currently it is at 146k miles. It has been burning 1 quart every 1k miles roughly. This is the car I started learning to do my own maintenance on, When I first got it I had the oil changed at a shop with Havoline - 1 quart per 1k miles burned. Then I changed it myself for the first time ever, O'Reilly's conventional 5w30 - 1 quart every 1k miles. Then I read the blessings of Valvoline Maxlife here.. I probably have done at LEAST 4-5 changes with it since I had the car, ranging from 2k miles-4k miles (the shorter interval was actually to get my Purolator off, and switch to PHM and a Fram TG. In the past 4k miles, I have switched to Pennzoil High Mileage the first 3k miles were the same 1 quart every 1k miles. I am coming up on 4k miles into this change.. and to my surprise.. I am still over halfway full on the dipstick, WOW. Many will say the MaxLife did the work, PHM finished it.. maybe, I will never say that MaxLife is a bad oil, I just think MaxLife did not fit my cars needs, it almost seems as Maxlife is Valvolines flagship oil, and honestly is better suited in cars with only minor/no oil burning, or moderate leaks. I Personally attribute Pennzoil High Mileage oil helping for a number of reasons, vs MaxLife. -Maxlife is resource conserving, PHM is not. -Maxlife is a semi syn, PHM is not (or at least not advertised as one) -I could be mistaken, but I believe PHM in the 5w30 flavor is a bit thicker compared to Maxlife. -Pennzoil always touts its cleaning ability, the chances that PHM freed a stuck ring, where maxlife did not? HIGHLY unlikely.. but maybe STILL possible, or maybe it did finish a job maxlife started. -Pennzoil contains a HIGH dose of Moly, which is supposed to "fill gaps and provide an anti-wear layer", MaxLife does not. HOWEVER I also feel like this is an unlikely explanation, I expect Valvoline Maxlife to contain some sort of similar antiwear agent that is not detected with UOA/VOA. All this is anecdotal of course, and I am in NO way bashing Maxlife, Or saying Pennzoil HM is better, instead.. I feel both oils have there places, and its up to the consumer to try and make an educated decision. (I actually feel like VML is an amazing oil to run in a newerish car with high miles, or an older car with no huge leaks/consumption as a preventive measure.) Take this for what you will, I will continue to watch the level and update as I can. I really wanted to do this as I have been planning on experimenting with different oils to see what happens, I still want to do some more runs of PHM, and also try some Quaker State Defy, Castrol High Mileage, and Mobil 1 High Mileage(When I have the extra money). Another reason for this is, we have tons of info and recommendations here for Valvoline MaxLife for people with consumption leaking issues, and I feel like the other big name High Mileage oils don't get nearly as much recognition. Share your thoughts, and also share if you've had any similar experiences or successes with different oils.
