    2025 Toyota Rav4 personal engine oil struggle.

    Then why does the 2019+ MK7 GTI/GLI share the oil pump with ea888-3B (which is a variable displacement oil pump, also controlled by the ECU)? 06H115105FS Where the early MK7's GTI use 06H115105GC (just your typical positive displacement pump)

    A reason not to pre-fill an oil filter

    my old VW with the CCTA engine had the filter upside down also. Never spilled oil when I pre-filled it. The trick is pre-fill, wait until the media allows the oil to pass through into the empty side, then pour off the excess (use some of the excess to lube the gasket), and then install...

    BMW patented their own screw to address DYIers

    Don't worry, some tool company will reverse engineer the screw head and make a bit available in the aftermarket, and as more companies copy the design, the price of the bit will go down.

    2025 Toyota Rav4 personal engine oil struggle.

    VW says differently. There is a reason why 508/509 oils are green. It has a chemical marker, that in the event of an engine warranty claim, VW will verify the marker in the oil sample to make the decision on claim approval, in case a BITOG member questioned a German's order to use 508/509, and...

    VW supposedly changed the oil pump on the 3rd gen EA888 engines when they went from 504/507 to requiring 508/509 And The Dynamic Force engine uses a Variable-Discharge oil pump.

    My concern with the new Camry

    Except the engine also provides propulsion also, as the engine be powering the wheels and charging the battery or powering the wheels with the aid of the electric motor. A beauty of the A25A-FXS is the thermal efficiency, of 41% at about 1900 rpms and somewhere in the low 2000 rpms, which is why...

    My concern with the new Camry

    TCCN did say on one of his videos, that in order for a dealership to get a warranty claim approved for an engine problem, they are required to drain a sample of oil and submit for UOA, to ensure the proper viscosity oil was used. Lake Speed Jr did a video on his channel talking about TGMO...

    Moly Level In Engine Oil

    Except, Castrol doesn't always do that. Longlife III is for 504/507 & C30. No MB approval. There probably wasn't an equivalent MB spec Castrol thought it would be a good business case to include getting current manufacturer approval But for Longlife IV FE 0w20, it has the 508/509, C20, as...

    Looking for An Amsoil Education

    Group III wasn't a thing back in the 70's. So, a little conventional oil was used to mix with the detergents. Not enough conventional to make a difference in the base stock performance GTL is more of a recent development in the Group III category

    Looking for An Amsoil Education

    Once upon a time, Amsoil (was called Amzoil before( prided themselves by only offering Group IV base stock oils only (purchasing the PAO from Exxon-Mobil). Their 10w40 was the first synthetic oil to meet API certification in early 70's, hence they used the tagline "First in Synthetics" Over...
