Hi, I've just changed my oil in my Z18XE Vectra C with 197,000 miles. It's in good condition and burns less than 1 litre of oil over a 10k interval. I've just drained Valvoline 5w/30 and replaced it with the above with a Mahle filter.
Less than 300 miles in and the level has dropped markedly, I'd say it's used at least half a litre. This is a concern, especially as it's on it's original cat and possibly even O2 sensors, I put their longevity down to it's low oil consumption amongst other things.
At 21 years old and with 197k it's obviously got some wear. Is this oil lacking the additives/seal conditioners of more expensive brands? I'm a bit miffed, the engine is running well, there's no reason to suggest there's some other issue with it. I'm planning to change just the oil in the next few days for something better.
Is there anyone else with experience or an opinion on the above brand and my issue? Thanks!
