13 GS350 13mo extreme short tripper VSP 0w20 5162m #4548232

Hey everyone,

Here is a UOA on my mothers 2013 GS350 AWD, car is driven locally with the occasional road trip once or twice per year. The majority of these miles are 2-3 miles at a time with TONS of cold starts and incomplete warmups. Car is located in Marquette, MI and had one winter on this OCI, oil was changed this spring and I just got around to sending the sample in.

I wanted to verify that a 1 year OCI was safe for her car, was mainly looking for fuel dillution and wear metals. Metals line up alright with universal averages, and fuel isn't out of control. Will continue with annual oil changes. Current fill is VSP 0w20 Max Life. This UOA isn't Max Life, just standard VSP. I'll sample again in the spring and likely yearly for trending.

Thanks for posting. Evidently, the fuel control system works well and the engine is a quality unit. For me, I expect that from Toyota. I have 2 Toyota engines now, a 1NZ-FE 1.5L and a 2UZ-FE 4.7L V8. The UOA for the V8 that works hard for a living was an excellent result.

Hey Luke,
Is that engine Direct Injected?

2GR-FSE has been using dual injection port and DI since 2006.

Bigj_16,

Someone already beat me to it, but yes the engine is direct injection, however it also uses port injection in combination with the direct injection.

I didn't mention this in the original post and it might be worth noting. I didn't do this oil change a friend of mine back home did in conjunction with swapping over winter for summer tires. I had asked him to make sure the car was good and warm to prevent any start up fuel dilution from tainting the sample. He did make sure that it was good and warm but part of doing so he drove the car pretty spirited with several WOT runs for about 20 minutes. I'm curious if that driving immediately before pulling the sample resulted in the small depression in flash point or is possibly making fuel dilution look worse than it is. Perhaps it didn't matter at all, I'm not sure. Next year I'll pull a sample myself without the WOT runs immediately beforehand and see what the numbers say. Either way I'm really impressed with this engine from a driving standpoint, it's night and day faster than my 2004 ES330!

If a short drive like that cleaned up any fuel dilution then it must have been nothing to worry about. Fuel probably starts to evaporate up out of the oil as soon as the oil starts to move around and warm up. Your idea of maybe cruising home after a short drive and doing the sample while the oil is warm but not all the way up to normal operating temperature might give you a better idea of what you're up against when short tripping.

Honestly, it has been shown on here that Blackstone has no idea how much fuel is in your sample.

It's good enough for what I need. Sure it's not GC, but it works for me. Viscosity still in grade, flash point at 380 tells me it's not terrible, especially considering the car never gets warm on 90% of its trips.

That's the way I feel, also.

If you all say so. But if you look back at threads on this topic the numbers they sometimes provide aren't even close.

Understood. But how much do you want to pay for a UOA? If this were an aircraft engine, wherein failure could be a bad thing, or a really expensive engine, wherein failure could be a bad thing :), I can know, within reasonable expectations, that based on what I smell, and a UOA from Blackstone, I have some fuel dilution. To me, in my truck engines, it doesn't matter if it's .5% or 1.5% or 2.5%. I know it has some, and I am just going to back up oil changes, until it is less. That is what I would do, anyway, if I did know the exact percentage.

I'm more concerned about viscosity staying in grade than the exact fuel percentage. That's what really matters to me, had it dropped out of grade I'd consider more often OCI or a heavier oil for my mom. It gets changed in the spring every year so that it gets a fresh start on warm weather with fresh oil. With the really low miles she puts on I think a 6 month OCI would be excessive. That being said I'm not comfortable going beyond a 1 year OCI out to 10,000 miles.

Sounds like a plan.

Was this oil entirely VSP ? With the lower sodium number and some moly from a previous fill it makes me wonder. The sodium number in particular


Cannot see signatures any longer so it doesn’t matter.
