Hello, BITOG experts,
This is my first post and I'd like to start by expressing my admiration for the depth of knowledge and expertise demonstrated by the community here when it comes to all things related to motor oils. It's truly impressive, and I haven't found a better source of advice on the web than right here at BITOG. With that said, I hope to benefit from your invaluable insights.
Earlier this year, I acquired a Mercedes-Benz GLC 300 with the M274 Engine (turbo 4 cyl) at approximately 55,000 miles on the odometer. According to the online service records, the vehicle has received regular oil changes at the Mercedes Benz dealership every 10,000 miles and has been maintained according to manufacturer's recommendations. One owner used as a personal vehicle.
I'm currently covered by an extended warranty provided by the nationwide used car retailer from whom I purchased the vehicle. My first oil change under this warranty took place at around 65,000 miles at their service department. They are responsible for the warranty, so I thought any issues that may arise would be their responsibility.
Recently, I discovered BITOG and became engrossed in the topic of motor oil. I'm continuously learning and expanding my knowledge in this area. It was during this process that I realized the service department where I bought the vehicle used an unapproved oil type for the car, specifically "Fram Oil" with a viscosity of 0W-30. There's speculation that this oil may be "Amelie Elixir" Given that the used car retailer performs oil changes at the time of sale, I've been running on this oil for nearly 15,000 miles now. I drive around 1200 miles a month.
I would greatly appreciate your recommendations on how to address this situation. I am looking for:
1. Minimizing the risk of LSPI.
2. Keeping the engine in good condition for as many years and miles as possible even after the warranty period. My extended warranty expires at 125,000 miles. M274 has a lot of history with piston getting cracked, which I realized after the purchase unfortunately.
Here are my specific questions:
1. Is "Fram Oil" at 0W-30 safe for this vehicle, despite it being unapproved? If it is safe, should I continue using it for future oil changes? They charge around $75 for the oil and filter change (Mann brand).
2. If this oil is not recommended for my vehicle, what would be your top choice for an alternative oil that has low calcium content and offers excellent long-term wear protection? Fuel efficiency is not a concern for me. Is Mobil 1 FS the right oil or is there a better one for me? I would probably go DIY and get one of those manual fluid extractors to do the job. I want to start 5,000 miles intervals.
3. What is the viscosity you would recommend? (Located in West NC)
As a side note, I've recently noticed a ticking noise during the first 15-20 minutes of my morning drive, which then gradually diminishes. I'm not certain if this noise has always been present or if I've only started noticing it recently. I tried using a can of Liqui Moly lifter additive, and after around 140 miles over two days, the noise has significantly reduced. It has been helpful thus far, and I'm eager to observe its long-term effects in the coming weeks.
Thank you for taking the time to read my post, and I'm grateful for all the insightful discussions taking place within this community.
