Owner reviews for engine oil

I have a 450k km 1.9 tdi, and a 300k km 1.6 tdi, i always use 5w30 castrol, no issue.

I really liked Valvoline, good quality, reasonble price.

My mom's impreza will loose oil between oil changes with 0w-20 and will be fine with 5w-30. It burns the thinner oil.

Valvoline Restore & Protect or Pennzoil Ultra Platinum are also great oils to run and clear up and baked on sludge.

My wife\u2019s 2012 Impreza is at 195k miles and I switched it to 0w-30 and then 5w-30 due to oil consumption. Was burning a quart every 1K miles on 0w-20, burns half that on 5w-30. I\u2019m actually considering going thicker.

using a heavier oil weight has been an old trick to help with oil consumption in Subarus for a long time now. I used to use Rotella 5w40 (before the reformulation) in my old 04 Baja Turbo and that particular oil was the best to keep the oil burning down.

I recently changed the engine and transmission oil in my car and opted for Liqui Moly, as from what I researched it withstands higher temperatures compared to the OEM.

SP certified oils have better LSPI protection than SN, and SP is what Subaru requires for this generation.

Kurzstrecke verhindert, dass das Öl nicht auf Temperatur kommt, dadurch bleiben Rückstände von Wasser etc, was du der Schlotze führt.

I use that Valvoline, sometimes throw in random fully synthetic oils I get in bulk from an auction. I feel like it contributed to a rear main seal leak. Thinking of switching to a 5w40
