Engine oil OEM Subaru or Lucas

Yes, it is good advice. When a new engine is breaking in, there is a lot more wear metals. It's not uncommon to see metallic flakes or shimmer in the oil during your first oil change. Parts wear/bed in. That's why there is a break-in period on almost, if not all new cars.

I did my first oil change at 1k miles on my BRZ; I saw a lot of metal shavings come out of the oil. The oil also had a metallic shimmer to it. This is totally normal, but I want to get rid of all of that so it is not circulating around the engine post-break in period.

My Miata has almost 300k on the original head gasket I started using the far right a few times ago and I don’t leak a lick of oil

I’m not going to argue with anyone about what it does but I’ve used Lucas for a long long time I have a 93 Chevy truck with 400k miles that I have never taken care of correctly I have run it out of oil overheated it overloaded it and abused and mistreated the engine in that truck and its still able to do any thing I need it to.

I use this on my 2003 Passat 1.8T probably every 2-3 oil changes. Motor has 269,000 miles and burns a smidgen of oil on startup. The Lucas seems to help a bit.

Used it for years in high mileage motors. 215,000 on a 1.8 turbo VW

used no oil between 5,000 mile changes.

Ok, so here’s my anecdote: a friend of mine had an old Ranger that had an oil pump failing. He didn’t want to pay me or anyone else to pull the engine and replace the pump so I suggested he just throw a bottle of this in there and see what happens.

Well, his oil light went off and oil pressure improved.

My '15 Forester will burn a quart of oil every 1000 miles if I run 0w20.

I switched to 5w30 and it's all good for 5000 miles

Well, some manufacturers do have way shorter oil change intervals than Euro manufacturers. The Subaru severe driving interval is 3000miles/6 months, and I do lots of short trips in a desert climate so I usually try to be around 3-4000 to stay on the safe side for warranty and whatnot.

So I drained the gearbox while I was there and refilled with 1/4 Lucas oil, the rest 80/90

I have a slow oil leak (something like a quart every 1,500 miles). Dealer quoted just under $3,000 for the fix when it was 17 years old with 110,000 miles. I'll just buy the occasional quart of oil.
